Got a Sleepy Arm?
Does your arm go to sleep when you raise it above your head? If there is any shortening or tightness in the pectoralis minor muscle, it can entrap the brachial nerve when you put your arm over your head. This can cause numbness in parts of your forearm, hand and fingers. Where the numbness occurs depends on what part of the nerve is entrapped. Pectoralis minor is fairly easy to treat with massage, and results are normally instant.
