I do remember when TOS started for me 2 years ago, I had symptoms in my legs too, but not anymore. From what I read there those symptoms do sound like TOS but of course we are not drs and what I learned in these 2 years from seeing so many drs and reading so much, is that this disease is very confusing and lots of things can overlap or mimic TOS. Rotator cuff issues for example can. Have you been evaluated by an orthopedic dr?
