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
