Botulinum toxin is a muscle-relaxing medication used to decrease spasticity related to multiple sclerosis and other neurological conditions. Botulinum toxin is derived from the bacterium Clostridium botulinum. There are three types of botulinum toxin available for therapeutic use.

Botox, the brand name of a toxin produced by the bacterium Clostridium botulinum, blocks signals from the nerves to the muscles. When Botox is injected into a muscle, it can no longer contract, causing the wrinkle to soften. Botox injections last from four to six months. Bruising is the most common side effect.

Botulism is an illness caused by a neurotoxin produced by the bacterium Clostridium botulinum. There are three types of botulism: food-borne, wound, and infant. Symptoms include muscle paralysis, dry mouth, constipation, slurred speech, and blurred vision. If food-borne and wound botulism are detected early enough, they may be treated with an antitoxin. Infant botulism is treated intravenously with BabyBIG (Botulism Immune Globulin).

Migraine headaches are severe headaches that are sensitive to light, sounds, and smells. Some people who suffer from migraines also have severe head pain. People also have symptoms of nausea and vomiting. Common migraine triggers may include:

• Certain foods
• Dehydration
• Changes in barometric pressure
• Stress
• Other phenomenon

They are diagnosed by a doctor if the headache pattern fits established migraine headache criteria. Over-the-counter (OTC) and prescription medications are sometime used to treat acute migraines. To prevent or reduce the frequency and severity of them doctors recommend supplements and prescription medications, for example:

• Blood pressure drugs
• Anti-seizure drugs
• Antidepressants

Lifestyle modification helps in migraine management. Many people who suffer from migraines get relief from their condition by keeping a headache diary, identifying and avoiding triggers, and taking appropriate medication.

Multiple sclerosis (MS) symptoms vary from person to person, and can last for days to months without periods of remission. Symptoms of MS include problems with the:

• Bowel
• Bladder
• Eyes (vision)

Muscle cramps are involuntarily and forcibly contracted muscles that do not relax. Extremely common, any muscles that have voluntary control, including some organs, are subject to cramp. Since there is such variety in the types of muscle cramps that can occur, many causes and preventative medications are known. Stretching is the most common way to stop or prevent most muscle cramps.

Muscle spasms are involuntary muscle contractions that come on suddenly and are usually quite painful. Dehydration, doing strenuous exercise in a hot environment, prolonged muscle use, and certain diseases of the nervous system may cause muscle spasms. Symptoms and signs of a muscle spasm include an acute onset of pain and a possible bulge seen or felt beneath the skin where the muscle is located. Gently stretching the muscle usually resolves a muscle spasm.

Temporomandibular joint (TMJ) syndrome is a disorder that causes symptoms like pain, clicking, and popping of the jaw. TMJ is caused by injury to the temporomandibular joint. Stress, poor posture, jaw trauma, genetic predisposition, and inflammatory disorders are risk factors for the condition. A variety of self-care measures (application of ice, use of over-the-counter pain medication, massage, relaxation techniques) and medical treatment options (dental splint, Botox, prescription medications, surgery) are available to manage TMJ. The prognosis of TMJ is good with proper treatment.
