Thoracic Outlet Syndrome (TOS) major symptoms are numbness and pain in the arms and hands, plus lack of blood flow to those areas. The brachial plexus, which carries both the nerves and blood vessels for that area, becomes impinged from the surrounding muscles and bones. Usually the pectoralis minor is a big player. The brachial plexus passes underneath it. Check for pec minor over activity associated with the lats, traps, rhomboids, and serratus. But if those are clear there are still the relationships to examine. One is the pectoralis major. The pec minor and major are synergists, and if the pec major is under working, the pec minor can overwork. That overworking can impinge the brachial plexus. Another relationship to consider is with the opposite internal oblique. If that is under active, the opposing pec minor can become over active in motions like twisting of the torso.
