hi, I do not have TOS but work with a vascular surgeon who repairs TOS, the surgery is very successful and our patients have always told me they wished they had the repair sooner, go to a peripheral vascular surgeon- have an Ultrasound with arm movements (the thech will have you raise your arm, turn your head and check the blood flow from a variety of positions- this will confirm ot rule out TOS on the spot.
there are a lot of great websites on TOS try a search on **********
