I don't have TOS but want to add that I had "compression" issues and it just meant compression by muscle and other tissue which was normal to keep nerves and blood vessels in place in my ankles. I had tarsal tunnel syndrome in both ankles, like carpal tunnel. It has much pain involved too. I had been 20-30 lbs. overweight for years and guess it caught up to me but then was also found to be pre-diabetic, bad combination.

Long story short, I had surgery on left ankle 1st, the muscle and tissue are cut, releasing the nerve and blood vessel but acutally they stay in place. It just gives everything there more room. And the surgeon said I "had a lot of nerve material", 4 branches instead of 2-3. But then the pain subsided in both legs and feet!! The Dr. said that happens sometimes. So I guess you can expect the unexpected and it can help explain the seemingly strange nerve symptoms of some TOS patients where their leg and foot is involved. (?)

Also, I think your Doctor's would have done other things right away, run more tests, talked to you about it immediately, if they had suspected cancer or anything dangerous in these tests. There would have not been any mailing of test results.
