Thoracic outlet syndrome (TOS) describes a group of conditions that are characterized by compression of the nerves, arteries, and veins in the lower neck and upper chest area. This can result in pain in the arms, shoulders, and neck. Currently, there is considerable disagreement about its diagnosis and treatment. A number of disorders have symptoms similar to those of TOS, including rotator cuff injuries, fibromyalgia, multiple sclerosis, complex regional pain syndrome, and tumors of the syrinx or spinal cord. Symptoms of this condition vary depending on the type. The different types include neurogenic, venous, and arterial thoracic outlet syndrome. There are many different causes of TOC. Symptoms usually occur between 20 and 50 years of age.[1]
