Does brachial plexus cause muscle pain?
Brachial plexus injuries typically stem from trauma to the neck, and can cause pain, weakness and numbness in the arm and hand. Brachial plexus injuries often heal well if they aren’t severe. Many people with minor brachial plexus injuries recover 90%–100% of the normal function of their arms.

Which muscles are found in the brachial region?
Once the brachial artery reaches the cubital fossa, it divides into its terminal branches: the radial and ulnar arteries of the forearm. The brachial artery and its branches supply the biceps brachii muscle, triceps brachii muscle, and coracobrachialis muscle.
Can brachial plexus effect legs?
PTS involves mainly the brachial plexus, the networks of nerves that extend from the spine through the neck, into each armpit and down the arms. These nerves control movements and sensations in the shoulders, arms, elbows, hands, and wrists. Other nerves in the arm or even the leg can also be involved.
