a note on leg symptoms-

I have bilateral TOS and occaisional issues with one of my feet. My neuro believes that if part of your contributing factor in getting TOS is a tendency towards muscle clenching or tightness, that this often can cause a similar problem in the lower extremities called piriformis syndrome, where the nerves to the legs are compressed by the piriformis muscle in your backside.

SO, his answer to 'does TOS cause symptoms in your legs' is no, but factors that cause you to have TOS can make it more likely that you also develop a condition such as piriformis syndrome.

For me, i believe years of undx'ed hypothyroid symptoms contributred to long term muscle clenching and tightness..even though it was a yoga injury that really put my TOS over the edge. I do get symptoms in one of my feet, but not nearly to the extent that I have them in my upper body.
