Thoracic Outlet Syndrome (TOS)
Thoracic Outlet Syndrome (TOS) is a bundle of symptoms that is caused by compression of the brachial plexus. The Thoracic Outlet is a passageway between the trunk and the arms on each side of the body. TO can result from injury to the neck, shoulder and back caused by an accident or automobile collision. Symptoms may include pain and numbness in the shoulder, hand and arm, coldness or extreme sensitivity to the hand, fingers turning pale or white; swelling, painful and stiff fingers. There are non-surgical and surgical treatments for TO. Usually nerve conduction studies are ordered to help diagnose the condition. Treatments may include physical therapy, heat, ultrasound, electrical stimulation, use of a sling, massage treatments, injections to the trigger points, rest, learning correct posture or relearning methods of performing work or activities, or avoidance or certain forms of work or activities.
