I doubt any doctor would say foot pain and numbness is attributed to TOS.

However, I think (for what ever its worth) that when you have TOS it messes up your entire bodies 'balance', feet go numb, head hurts, whatever... Since I have vascular TOS I believe the entire right side of my body is a little 'off kilter'. For example, even though my vains in the shoulder and upper arm are clearly negitively effected by TOS, nobody can explain why the veins in my right leg are distended as well. Probably just vericose veins starting, or its just one of those things...
