Brachial plexus injuries from birth can damage the nerves in your child's arm. The brachial plexus is a network of nerves near the neck. The nerves of the arm branch out from here. The plexus can be damaged during birth if the neck is stretched in a difficult delivery.
Brachial plexus injuries cause:
Weakness in the arm
Loss of feeling in the arm
Children can fully recover with daily therapy. Treatments include exercises to increase motion and strength.
If your child shows no improvement in the first 3 to 6 months or therapy, surgery may be needed to repair the injured nerves
