I understand where you all are coming from, but have a somewhat different perspective. I do have a lot of problems outside the TOS area. I get unusual tension up and down the left side of my body. Also, my entire jaw and much of my neck on both sides.

I do believe that TOS can have secondary affects that spread out. But I also don't chalk up all of my issues to that. In fact, I feel like the tension problems precede TOS. e.g., I have muscle tension which in turn causes: TOS, neck pain, lower back pain and sciatica.
