I have had an MRI of the neck and my results were deg. disc disease in C4-C7 and slight bulging at those levels. I also have a reversal of the cervical lordosis which just adds to the spasming/constriction of the neck muscles.

When I had my EMG, they tested in C8 as well but as far as my results for the EMG, they were normal according to my Neuro. BUT my pain management Doc would like to redo the test as he feels it should have been done on both sides.

To answer your question, I do not get color changes in my hands. So maybe this means I don't in fact have "TOS." Doc does feel I have an impingement going on in the thoracic outlet, or actually I should say, the neck/collarbone area which is causing all my pain in my thoracic outlet. He also said I should have Trigger Point Injections as he felt numerous areas. He also feels this is directly related to my posture and repetitive strain and not extra cervical ribs, as I had xrays done and none showed.

ETA: not that age matters, but I am 23.
