Foot Pain Glossary of Terms

The following are health and medical definitions of terms that appear in the Foot Pain article.

Absorb: 1. To take something in, as through the skin or the intestine.
2. To react with radiation and reduce it in intensity, as with a dose of radiation or transmitted light.
See also: Absorbed dose; Absorption; Malabsorption; Reabsorption.

Absorption: Uptake. In the biomedical sciences, absorption has diverse specific meanings.
See the entire definition of Absorption

Acetaminophen: A pain reliever and fever reducer. Brand name: Tylenol. The exact mechanism of action of acetaminophen is not known. Acetaminophen relieves pain by elevating the pain threshold (that is, by requiring a greater amount of pain to develop before it is felt by a person). Acetaminophen reduces fever through its action on the heat-regulating center (the "thermostat") of the brain. Generic is available.

Achilles: In Greek mythology, the hero who was thought to have some special medical knowledge. Achilles studied medicine with Chiron , the centaur, who invented it.
See the entire definition of Achilles

Acute: Of abrupt onset, in reference to a disease. Acute often also connotes an illness that is of short duration, rapidly progressive, and in need of urgent care.
See the entire definition of Acute

Ankle: The ankle joint is complex. It is made up of two joints: the true ankle joint and the subtalar joint:
See the entire definition of Ankle

Ankle joint: The ankle joint is complex. It is made up of two joints: the true ankle joint and the subtalar joint:

  • The true ankle joint is composed of 3 bones: the tibia which forms the medial (inside) portion of the ankle; the fibula which forms the lateral (outside) portion of the ankle; and the talus underneath. The true ankle joint is responsible for the up-and-down motion of the foot.
  • The subtalar joint is under the true ankle joint and consists of the talus on top and calcaneus on the bottom. The subtalar joint is responsible for the side-to-side motion of the foot.

See the entire definition of Ankle joint

Arthritis: Inflammation of a joint. When joints are inflamed they can develop stiffness, warmth, swelling, redness and pain. There are over 100 types of arthritis. (see osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis, lupus, gout, pseudogout).

Aspirin: A good example of a tradename that entered into the language, Aspirin was once the Bayer trademark for acetylsalicylic acid .
See the entire definition of Aspirin

Athlete's foot: A skin infection caused by a fungus called Trichophyton which can thrive and infect the upper layer of the skin when the feet (or other areas of the body) remain moist, warm, and irritated. The fungus can be found on floors and in socks and clothing and can be spread from person to person by contact with these objects. However, without proper growing conditions (a warm, moist environment), the fungus will not infect the skin. For more information, see: Athlete's Foot.

Bacteria: Single-celled microorganisms which can exist either as independent (free-living) organisms or as parasites (dependent upon another organism for life).
See the entire definition of Bacteria

Bacterial: Of or pertaining to bacteria. For example, a bacterial lung infection.

Blister: A collection of fluid underneath the top layer of skin (epidermis). One that is more than 5 mm in diameter with thin walls and is full of watery fluid is called a bulla or a bleb. There are many causes of blisters including burns , vesicant agents, friction forces, and diseases of the skin.
See the entire definition of Blister

Bone scan: A technique to create images of bones on a computer screen or on film. A small amount of radioactive material is injected and travels through the bloodstream. It collects in the bones, especially in abnormal areas of the bones, and is detected by special instrument called a scanner. The image of the bones is recorded on a special film for permanent viewing.
See the entire definition of Bone scan

Bruise: A bruise or "contusion" is an traumatic injury of the soft tissues which results in breakage of the local capillaries and leakage of red blood cells. In the skin it can be seen as a reddish-purple discoloration that does not blanch when pressed upon. When a bruise fades it becomes green and brown as the body metabolizes the blood cells in the skin. It is best treated with local application of a cold pack immediately after injury. Also called a contusion.

Bursa: A closed fluid-filled sac that functions to provide a gliding surface to reduce friction between tissues of the body. When the bursa becomes inflamed, the condition is known as bursitis. Bursa is the Greek word for "a wine skin."

Cardiovascular: The circulatory system comprising the heart and blood vessels which carries nutrients and oxygen to the tissues of the body and removes carbon dioxide and other wastes from them.
See the entire definition of Cardiovascular

Chronic: This important term in medicine comes from the Greek chronos, time and means lasting a long time.
See the entire definition of Chronic

Circulation: The movement of fluid in a regular or circuitous course. Although the noun "circulation" does not necessarily refer to the circulation of the blood, for all practical purposes today it does. Heart failure is an example of a problem with the circulation.

Compression: 1. The act of pressing together. As in a compression fracture, nerve compression, or spinal cord compression.
2. To shorten in time. In embryology, there may be compression of development with some stages even omitted.

Contraction: The tightening and shortening of a muscle.

Contusion: Another name for a bruise. What is a bruise ? A bruise, or contusion, is caused when blood vessels are damaged or broken as the result of a blow to the skin (be it bumping against something or hitting yourself with a hammer). The raised area of a bump or bruise results from blood leaking from these injured blood vessels into the tissues as well as from the body's response to the injury. A purplish, flat bruise that occurs when blood leaks out into the top layers of skin is referred to as an ecchymosis.

Corns: Small calloused areas of skin caused by local pressure irritating tissue over a bony prominence. Corns most commonly occur over a toe where they form what is referred to as a hard corn. Between the toes, pressure can form a soft corn of macerated skin which often yellows.
See the entire definition of Corns

Diabetes: Refers to diabetes mellitus or, less often, to diabetes insipidus . Diabetes mellitus and diabetes insipidus share the name "diabetes" because they are both conditions characterized by excessive urination (polyuria).
See the entire definition of Diabetes

Diagnosis: 1 The nature of a disease ; the identification of an illness. 2 A conclusion or decision reached by diagnosis. The diagnosis is rabies . 3 The identification of any problem. The diagnosis was a plugged IV.
See the entire definition of Diagnosis

Drain: A device for removing fluid from a cavity or wound. A drain is typically a tube or wick. As a verb, to allow fluid to be released from a confined area.

Essential: 1. Something that cannot be done without.
2. Required in the diet, because the body cannot make it. As in an essential amino acid or an essential fatty acid.
3. Idiopathic. As in essential hypertension. "Essential" is a hallowed term meaning "We don't know the cause."

Fascia: A flat band of tissue below the skin that covers the underlying tissues and separates different layers of tissue. Fascia encloses muscles. Inflammation of the fascia is referred to as fasciitis .
See the entire definition of Fascia

Fasciitis : Inflammation of the fascia (a lining tissue under the skin that covers a surface of underlying tissues).
See the entire definition of Fasciitis

Flat feet: A condition of the feet in which the arch of the instep is flattened and the entire sole touches the ground.
See the entire definition of Flat feet back to top

Focal: Pertaining to a focus which in medicine may refer to:
1. The point at which rays converge as, for example, in the focal point.
2. A localized area of disease. A focal cancer is limited to one specific area.

Foot pain: Foot pain is the sensation of discomfort in the foot arising from disorders or injury to any of the structures in the foot including bones, nerves, muscles, blood vessels, or connective tissue . There are numerous and varied causes for foot pain, since the foot is an extremely complex anatomic structure made up of 26 bones and 33 joints along with 19 muscles and 107 ligaments.
See the entire definition of Foot pain

Fracture: A break in bone or cartilage. Although usually the result of trauma, a fracture can be caused by an acquired disease of bone such as osteoporosis or by abnormal formation of bone in a disease such as osteogenesis imperfecta ("brittle bone disease"). Fractures are classified according to their character and location as, for example, a greenstick fracture of the radius.
See the entire definition of Fracture

Fungi: Plural of fungus.

Fungus: A single-celled or multicellular organism. Fungi can be true pathogens (such as histoplasmosis and coccidioidomycosis) that cause infections in healthy persons or they can be opportunistic pathogens (such as aspergillosis, candidiasis, and cryptococcosis) that cause infections in immunocompromised persons (including cancer patients, transplant recipients, and persons with AIDS). An example of a common fungus is the yeast organism which causes thrush and diaper rash (diaper dermatitis). Fungi are also used for the development of antibiotics, antitoxins, and other drugs used to control various human diseases.

Gait: A manner of walking. Observation of the gait can provide clues to a number of diagnoses including Parkinson disease, cerebral palsy, congenital dislocation of the hip, and stroke.

Gout: Condition characterized by abnormally elevated levels of uric acid in the blood, recurring attacks of joint inflammation (arthritis), deposits of hard lumps of uric acid in and around the joints, and decreased kidney function and kidney stones. Uric acid is a breakdown product of purines, that are part of many foods we eat. The tendency to develop gout and elevated blood uric acid level (hyperuricemia) is often inherited and can be promoted by obesity, weight gain, alcohol intake, high blood pressure, abnormal kidney function, and drugs. The most reliable diagnostic test for gout is the identification of crystals in joints, body fluids and tissues.

Hansen's disease: See: Hansen disease.

Hygiene: The science of preventive medicine and the preservation of health. From the name of Hygeia, the daughter of Asklepios, the Greek god of medicine (whose staff with entwined snake is the symbol of medicine). Asklepios (known to the Romans as Aesculapius) had a number of children including not only Hygeia but also Panaceia, the patroness of clinical medicine. Hygeia also followed her father into medicine. As the patroness of health, Hygeia was charged with providing a healthy environment to prevent illness. In Greek, "hygieia" means health.

Ibuprofen: A non-steroidal anti-inflammatory drug (NSAID) commonly used to treat pain, swelling, and fever. Common brand names for Ibuprofen include Advil, Motrin, and Nuprin.

Indicate: In medicine, to make a treatment or procedure advisable because of a particular condition or circumstance. For example, certain medications are indicated for the treatment of hypertension during pregnancy while others are contraindicated.

Infection: The growth of a parasitic organism within the body. (A parasitic organism is one that lives on or in another organism and draws its nourishment therefrom.) A person with an infection has another organism (a "germ") growing within him, drawing its nourishment from the person.
See the entire definition of Infection

Inflammation: A basic way in which the body reacts to infection , irritation or other injury, the key feature being redness, warmth, swelling and pain . Inflammation is now recognized as a type of nonspecific immune response .
See the entire definition of Inflammation

Inflammatory response: A fundamental type of response by the body to disease and injury, a response characterized by the classical signs of "dolor, calor, rubor, and tumor " -- pain , heat (localized warmth), redness, and swelling.
See the entire definition of Inflammatory response

Ingrown toenail: A common disorder that occurs when the edge of the toenail grows into the skin of the toe particularly on the big (great) toe. The corner of the nail curves down into the skin, often due to mis-trimming of the nail, or due to shoes that are too tight. An ingrown toenail can be painful and lead to infection.
See the entire definition of Ingrown toenail back to top

Injury: Harm or hurt. The term "injury" may be applied in medicine to damage inflicted upon oneself as in a hamstring injury or by an external agent on as in a cold injury. The injury may be accidental or deliberate, as with a needlestick injury. The term "injury" may be synonymous (depending on the context) with a wound or with trauma.

Itching: An uncomfortable sensation in the skin that feels as if something is crawling on the skin or in the skin, and makes the person want to scratch the affected area.
See the entire definition of Itching

Joint: A joint is the area where two bones are attached for the purpose of motion of body parts. A joint is usually formed of fibrous connective tissue and cartilage. An articulation or an arthrosis is the same as a joint.
See the entire definition of Joint

Kinetics: Kinetics (with an "s" at the end) refers to the rate of change in a biochemical (or other) reaction, the study of reaction rates. Kinetics is a noun. It is distinct from "kinetic" (an adjective) meaning with movement. The opposite of kinetic is akinetic meaning without movement. In neurology, kinetic and akinetic serve to denote the presence or absence of movement. Kinetic comes from the Greek word "kinesis" for motion. The term "akinetic" is put together from the prefix "a-" meaning "without" + "kinesis" = without motion. Kinesis is verbatim from the Greek "kinesis."

Leg: In popular usage, the leg extends from the top of the thigh down to the foot. However, in medical terminology, the leg refers to the portion of the lower extremity from the knee to the ankle.
See the entire definition of Leg

Ligament: A ligament is a tough band of connective tissue that connects various structures such as two bones.
See the entire definition of Ligament

Longitudinal: The word come from the Latin longitudo meaning length. Hence, longitudinal means along the length, running lengthwise, or (by extension) over the course of time.

Lower leg: The lower leg is the bottom segment of the leg: the part below the knee.
See the entire definition of Lower leg

Mallet: The malleus.

Morton's neuroma: A swollen inflamed nerve in the ball of the foot, usually between the base of the second and third toes (known as the third intermetatarsal space), caused by chronic compression of a branch of the plantar nerve between the ends of the metatarsal bones. The disorder is especially common in women who wear high-heeled and/or narrow shoes.
See the entire definition of Morton's neuroma

MRI: Abbreviation and nickname for magnetic resonance imaging. For more information, see: Magnetic Resonance Imaging; Paul C. Lauterbur; Peter Mansfield.

Muscle: Muscle is the tissue of the body which primarily functions as a source of power. There are three types of muscle in the body. Muscle which is responsible for moving extremities and external areas of the body is called "skeletal muscle." Heart muscle is called "cardiac muscle." Muscle that is in the walls of arteries and bowel is called "smooth muscle."

Nail: In medicine, there are two types of nails. One is just a plain old metal nail used to hold 2 or more pieces of bone together, for example, after a fracture. The other type of nail is the horny plate on the end of the finger or toe. Each nail anatomically has a body, lateral nail folds (on the sides), a lunula (the little moon-shaped feature at the base), and a proximal skin fold (at the base).
See the entire definition of Nail

Naproxen : A non-steroidal anti-inflammatory drug (NSAID) used for the management of mild to moderate pain, fever, and inflammation . Naproxen blocks the enzyme cyclooxygenase that makes prostaglandins, resulting in lower concentrations of prostaglandins. As a consequence, inflammation, pain and fever are reduced. Brand names for naproxen include Anaprox, Naprelan, Naprosyn, and Aleve.
See the entire definition of Naproxen

Neuroma: A tumor that arises in nerve cells.

Neuropathy: Any and all disease or malfunction of the nerves.

Onset: In medicine, the first appearance of the signs or symptoms of an illness as, for example, the onset of rheumatoid arthritis . There is always an onset to a disease but never to the return to good health. The default setting is good health.
See the entire definition of Onset

Open wound: An injury that is exposed due to broken skin. An open wound is at high risk for infection.
See the entire definition of Open wound

Osteoarthritis: A type of arthritis caused by inflammation, breakdown, and eventual loss of cartilage in the joints. Also known as degenerative arthritis.

Pain: An unpleasant sensation that can range from mild, localized discomfort to agony. Pain has both physical and emotional components. The physical part of pain results from nerve stimulation. Pain may be contained to a discrete area, as in an injury, or it can be more diffuse, as in disorders like fibromyalgia . Pain is mediated by specific nerve fibers that carry the pain impulses to the brain where their conscious appreciation may be modified by many factors.
See the entire definition of Pain

Peripheral: Situated away from the center, as opposed to centrally located.
See the entire definition of Peripheral

Peripheral neuropathy : A problem with the functioning of the nerves outside the spinal cord. Symptoms may include numbness, weakness, burning pain (especially at night), and loss of reflexes.
See the entire definition of Peripheral neuropathy

Plantar: Having to do with the sole of the foot.
See the entire definition of Plantar

Plantar fasciitis: Inflammation of the plantar fascia (fasciitis), the "bowstring-like" tissue in the sole of the foot stretching from the heel to the front of the foot.
See the entire definition of Plantar fasciitis

Prophylactic: A preventive measure. The word comes from the Greek for "an advance guard," an apt term for a measure taken to fend off a disease or another unwanted consequence.
See the entire definition of Prophylactic

Resistance: Opposition to something, or the ability to withstand it. For example, some forms of staphylococcus are resistant to treatment with antibiotics.
See the entire definition of Resistance

Scan: As a noun, the data or image obtained from the examination of organs or regions of the body by gathering information with a sensing device.
See the entire definition of Scan

Sensation: In medicine and physiology , sensation refers to the registration of an incoming ( afferent ) nerve impulse in that part of the brain called the sensorium , which is capable of such perception. Therefore, the awareness of a stimulus as a result of its perception by sensory receptors. (Sensory is here synonymous with sensation.)
See the entire definition of Sensation

Shin: 1. The tibia, the larger of the two bones in the lower leg.
2. The anterior aspect (front) of the tibia.

Sprain: An injury to a ligament that results from overuse or trauma. Sprains occurs when there is a stretch or tear in one or more ligaments, slightly elastic bands of tissue that keep the bones in place while permitting movement at a joint. The treatment of a sprain involves applying ice packs, resting and elevating the involved joint, and using anti-inflammatory medications. Depending on the severity and location of the sprain, support bracing can help. Local cortisone injections are sometimes given for persistent inflammation. Activity may be resumed gradually. Ice application after activity can reduce or prevent recurrent inflammation. Occasionally, supportive bracing can prevent reinjury. In severe sprains, orthopedic surgical repair may be performed.

Strain: 1. An injury to a tendon or muscle resulting from overuse or trauma. 2. A hereditary tendency that originated from a common ancestor. 3. To exert maximum effort. 4. To filter.

Stress: Forces from the outside world impinging on the individual. Stress is a normal part of life that can help us learn and grow. Conversely, stress can cause us significant problems.
See the entire definition of Stress

Stress fracture: A fracture caused by repetitive stress, as may occur in sports, strenuous exercise, or heavy physical labor. Stress fractures are especially common in the metatarsal bones of foot, particularly in runners. Osteoporosis increases the possibility of stress fractures. Treatment is by rest, disuse, and sometimes splinting or casting to prevent reinjury during healing.

Surgery: The word "surgery" has multiple meanings. It is the branch of medicine concerned with diseases and conditions which require or are amenable to operative procedures. Surgery is the work done by a surgeon. By analogy, the work of an editor wielding his pen as a scalpel is s form of surgery. A surgery in England (and some other countries) is a physician's or dentist's office.
See the entire definition of Surgery

Tear: A drop of the salty secretion of the lacrimal glands which serves to moisten the conjunctiva and cornea.

Tendon: The tissue by which a muscle attaches to bone. A tendon is somewhat flexible, but fibrous and tough. When a tendon becomes inflamed, the condition is referred to as tendinitis or tendonitis. Inflamed tendons are at risk for rupture.
See the entire definition of Tendon

Toenail: A toenail is produced by living skin cells in the toe. A toenail consists of several parts including the nail plate (the visible part of the nail), the nail bed (the skin beneath the nail plate), the cuticle (the tissue that overlaps the plate and rims the base of the nail), the nail folds (the skin folds that frame and support the nail on three sides), the lunula (the whitish half-moon at the base of the nail) and the matrix (the hidden part of the nail unit under the cuticle).
See the entire definition of Toenail

Transverse: In anatomy, a horizontal plane passing through the standing body so that the transverse plane is parallel to the floor.
See the entire definition of Transverse

Trauma: Any injury , whether physically or emotionally inflicted. "Trauma" has both a medical and a psychiatric definition. Medically, "trauma" refers to a serious or critical bodily injury, wound, or shock . This definition is often associated with trauma medicine practiced in emergency rooms and represents a popular view of the term. In psychiatry , "trauma" has assumed a different meaning and refers to an experience that is emotionally painful, distressful, or shocking, which often results in lasting mental and physical effects.
See the entire definition of Trauma

Turf toe: An injury to the big toe due to forced hyperextension (upward bending back) of the toe. The damage is to the capsule of the joint (the first metatarsophalangeal joint) and the ligaments that connect the big toe to the foot. Hyperflexible shoes predispose to the injury. The big toe is painful, tender and swollen. Treatment is with icing, rest and anti-inflammatory medication. Taping of the big toe and a stiff insole insert in the shoe may help prevent hyperextension of the toe. Turf toe is so named for its occurrence on the artificial playing surfaces used in American football. Turf toe also occurs in other sports played on artificial turf, in grass sports, and the martial arts. Also known medically as a metatarsophalangeal joint sprain.
See the entire definition of Turf toe

Tylenol: See: Acetaminophen.

Viral: Of or pertaining to a virus. For example, "My daughter has a viral rash ."
See the entire definition of Viral

Virus: A microorganism smaller than a bacteria, which cannot grow or reproduce apart from a living cell. A virus invades living cells and uses their chemical machinery to keep itself alive and to replicate itself. It may reproduce with fidelity or with errors (mutations)-this ability to mutate is responsible for the ability of some viruses to change slightly in each infected person, making treatment more difficult.
See the entire definition of Virus

Viruses: Small living particles that can infect cells and change how the cells function. Infection with a virus can cause a person to develop symptoms. The disease and symptoms that are caused depend on the type of virus and the type of cells that are infected.

X-ray: 1. High-energy radiation with waves shorter than those of visible light. X-rays possess the properties of penetrating most substances (to varying extents), of acting on a photographic film or plate (permitting radiography), and of causing a fluorescent screen to give off light (permitting fluoroscopy). In low doses X-rays are used for making images that help to diagnose disease, and in high doses to treat cancer . Formerly called a Roentgen ray. 2. An image obtained by means of X-rays.

Foot Pain

What is a bruise?

You fall off your bike, bang your shin on the coffee table (that you swore you would move months ago) or run into a wall and wake up with a wallop of a bruise. What is a bruise, and what can you do about it? A bruise (medically referred to as a contusion) is caused when tiny blood vessels are damaged or broken as the result of a blow to the skin (be it bumping against something or hitting yourself with a hammer). The raised area of a bump or bruise results from blood leaking from these injured blood vessels into the tissues as well as from the body's response to the injury. A purplish, flat bruise that occurs when blood leaks out into the top layers of skin is referred to as an ecchymosis.

Why do bruises occur more frequently in some people than in others?

The injury required to produce a bruise varies with age. While it may take quite a bit of force to cause a bruise in a young child, even minor ...
