The brachial plexus is a group of nerves that run from the lower neck through the upper shoulder area. These nerves provide the shoulder, arm, forearm, and hand with movement and sensation.
Damage to the brachial plexus nerves can cause muscle and sensation problems that are often associated with pain in the same area. Symptoms may include:
- Loss of feeling or sensation in your arm or hand
- Trouble moving your arm
- Lack of muscle control in the arm, hand, or wrist
