Clinical Definition

Brachial neuritis is a type of neuropathy in which inflammation of the brachial plexus develops. The etiology of the inflammation is often unknown. In addition to inflammation, a sudden onset of pain and weakness in the shoulders and hands occurs. Although the condition may occur bilaterally, it is more frequently unilateral.

In Our Own Words

Brachial neuritis is a rare nerve condition that affects the shoulders and hands. The brachial plexus is a bundle of nerves near the shoulder and neck.  It controls movement and feeling in the shoulders, hand and wrist. When brachial neuritis develops, the nerves become inflamed, which causes pain, numbness and a loss of muscle control in the shoulders and hands. The cause of the condition is unknown. Symptoms can last for months.
