You can tell if you have a broken foot by medical examination that includes imaging studies. The healing and recovery time for a broken bone in the foot depends upon the type of fracture and the bones broken.
Thrombocytopenia (Low Platelet Count)
Thrombocytopenia (low platelet count) refers to a decreased number of platelets in the blood. Symptoms of thrombocytopenia include: Increased bruising Spontaneous bleeding Small, purple spots under the skin called purpura There are many causes of thrombocytopenia such as decreased platelet production (viral infections for example rubella, mumps, chickenpox, hepatitis C, and HIV); increased platelet destruction or consumption (for example sulfonamide antibiotics, heparin, blood transfusions, and lupus); or increased splenic sequestration (enlarged spleen due to conditions for example liver disease, blood cancers, and more). Treatment of thrombocytopenia depends on the cause.
Blood Clots (in the Leg)
Blood clots can occur in the venous and arterial vascular system. Blood clots can form in the heart, legs, arteries, veins, bladder, urinary tract and uterus. Risk factors for causes of blood clots include high blood pressure and cholesterol, diabetes, smoking, and family history. Symptoms of a blood clot depend on the location of the clot. Some blood clots are a medical emergency. Blood clots are treated depending upon the cause of the clot. Blood clots can be prevented by lowering the risk factors for developing blood clots.
Edema is the swelling of tissues as a result of excess water accumulation. Peripheral edema occurs in the feet and legs. There are two types of edema, non-pitting edema and pitting edema. Causes of pitting edema is caused by systemic diseases (most commonly involving the heart, liver, and kidneys), and medications. Local conditions that cause edema are thrombophlebitis and varicose veins. Edema or swelling of the legs, feet, ankles, and face are common during pregnancy. Idiopathic edema is edema in which the cause is not known. Pitting edema is scored on pitting edema measurement scales. Edema is generally treated with medication.

Hematoma vs. Bruise
A hematoma is a localized collection of blood in the tissues of the body outside of the blood vessels. A bruise is a discoloration of the skin that is a result of leakage of blood from capillaries into the skin. Bruises and hematomas are most commonly caused by injury to the tissues. Both minor hematomas and bruises are common results of activities from daily living and usually require no specific treatment. Seek medical care for any hematoma or spontaneous bruising that occurs without any known cause.
A bruise, or contusion, is caused when blood vessels are damaged or broken as the result of a blow to the skin.

Cauliflower ear, or "boxer's ear," is caused by an injury to the ear, usually by blunt trauma from sports such as boxing, wrestling, or martial arts. When hematomas form, infection and eardrum injury may occur in addition to hearing loss if not treated. Treatment goals are to drain blood from hematomas, treat infection, and at times administer antibiotics to prevent further infection.
Transient Ischemic Attack (TIA, Mini-Stroke)
When a portion of the brain loses blood supply, through a blood clot or embolus, a transient ischemic attack (TIA, mini-stroke) may occur. If the symptoms do not resolve, a stroke most likely has occurred. Symptoms of TIA include: confusion, weakness, lethargy, and loss of function to one side of the body. Risk factors for TIA include vascular disease, smoking, high blood pressure, high cholesterol, and diabetes. Treatment depends upon the severity of the TIA, and whether it resolves.
Arthritis, bursitis, IT band syndrome, fracture, and strain are just some of the causes of hip pain. Associated symptoms and signs include swelling, tenderness, difficulty sleeping on the hip, and loss of range of motion of the hip.

Idiopathic Thrombocytopenic Purpura (ITP)
Idiopathic means that the cause of the condition isn't known. Thrombocytopenic means there's a lower than normal number of platelets in the blood. Purpura refers to purple bruises caused by bleeding under the skin. Idiopathic thrombocytopenic purpura (ITP) is a bleeding condition in which the blood doesn't clot as it should. This is due to a low number of blood cell fragments called platelets.
Hydrocephalus is an abnormal buildup of cerebrospinal fluid (CSF) in the ventricles of the brain. The fluid is often under increased pressure and can compress and damage the brain. Symptoms of hydrocephalus vary with age, progression of the disease, and individual tolerance to the condition. Hydrocephalus is most often treated by surgery in which a shunt system is inserted.
