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
- Numbness
- Pain
- Burning or tingling
- Muscle weakness
- Sensitivity to touch
Treatment aims to treat any underlying problem, reduce pain and control symptoms.

Sarcoidosis is a disease that leads to inflammation, usually in your lungs, skin, or lymph nodes. It starts as tiny, grain-like lumps, called granulomas. Sarcoidosis can affect any organ in your body.
No one is sure what causes sarcoidosis. It affects men and women of all ages and races. It occurs mostly in people ages 20 to 50, African Americans, especially women, and people of Northern European origin.
Many people have no symptoms. If you have symptoms, they may include
- Cough
- Shortness of breath
- Weight loss
- Night sweats
- Fatigue
Tests to diagnose sarcoidosis include chest x-rays, lung function tests, and a biopsy. Not everyone who has the disease needs treatment. If you do, prednisone, a type of steroid, is the main treatment.
