Thoracic Outlet Syndrome (TOS) pain relief is usually achieved by treating structures other than a cervical rib.  Fortunately even though cervical rib is the most commonly thought of reason for TOS it is actually the least common cause of it.  More common sources include scalene (neck) muscle spasm, sympathetic over activity (resulting in cold sensations and weather sensitive pain), nerve irritation, and ligamentous strain.  The good news is that unlike TOS from cervical rib surgery is not required for these other perpetrators and treatment results are much more effective than is achieved by rib resection.  Make no mistake about it,  TOS is hard to treat and results don’t occur over night but with concerted effort the condition can and does improve.   Visit piedmontpmr.com to learn more about diagnosis and treatment options of TOS for Greenville, Spartanburg, and Anderson patients.
