In a typical case of Charcot’s Joint, the foot has lost most sensation. The person no longer can feel pain in the foot and loses the ability to sense the position of the joint. Also, the muscles lose their ability to support the joint properly. The foot then becomes unstable, and walking just makes it worse.
An injury, such as a twisted ankle, may make things even worse. Joints grind on bone. The result is inflammation, which leads to further instability and then dislocation. Finally, the bone structure of the foot collapses. Eventually, the foot heals on its own, but because of the breakdown of the bone, it heals into a deformed foot.
People at risk for Charcot’s Joint are those who already have neuropathy. They should be aware of symptoms such as:
Early treatment can stop bone destruction and aid healing.
Most often, cranial neuropathy affects the nerves that control the eye muscles. The neuropathy begins with pain on one side of the face near the affected eye. Later, the eye muscle becomes paralyzed. Double vision results. Symptoms of this type of neuropathy usually get better or go away within 2 or 3 months.
Carpal tunnel syndrome is probably the most common compression mononeuropathy. It occurs when the median nerve of the forearm is compressed at the wrist. Symptoms of this type of neuropathy include numbness, swelling, or prickling in the fingers with or without pain when driving a car, knitting, or resting at night. Simply hanging your arm by your side usually stops the pain within a few minutes. If the symptoms are severe, an operation can give complete relief from pain.
Femoral neuropathy occurs most often in people with type 2 diabetes. A pain may develop in the front of one thigh. Muscle weakness follows, and the affected muscles waste away. A different kind of neuropathy that also affects the legs is called diabetic amyotrophy. In this case, weakness occurs on both sides of the body, but there is no pain. Doctors do not understand why it occurs, but blood vessel disease may be the cause.
Focal Neuropathy affects a nerve or group of nerves causing sudden weakness or pain. It can lead to double vision, a paralysis on one side of the face called Bell’s palsy, or a pain in the front of the thigh or other parts of the body.
