Peripheral Nerve Disorders

Also called: Neuritis, Peripheral neuritis, Peripheral neuropathy

Your peripheral nerves are the ones outside your brain and spinal cord. Like static on a telephone line, peripheral nerve disorders distort or interrupt the messages between the brain and the rest of the body.

There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves. Some are the result of other diseases, like diabetic nerve problems. Others, like Guillain-Barre syndrome, happen after a virus infection. Still others are from nerve compression, like carpal tunnel syndrome or thoracic outlet syndrome. In some cases, like complex regional pain syndrome and brachial plexus injuries, the problem begins after an injury. Some people are born with peripheral nerve disorders.

Symptoms often start gradually, and then get worse. They include

Treatment aims to treat any underlying problem, reduce pain and control symptoms.

Wrist Injuries and Disorders

Your wrist is made up of eight small bones known as carpals. They support a tube that runs through your wrist. That tube, called the carpal tunnel, has tendons and a nerve inside. It is covered by a ligament, which holds it in place.

Wrist pain is common. Repetitive motion can damage your wrist. Everyday activities like typing, racquet sports or sewing can cause pain, or even carpal tunnel syndrome. Wrist pain with bruising and swelling can be a sign of injury. The signs of a possible fracture include misshapen joints and inability to move your wrist. Some wrist fractures are a result of osteoporosis.
