I recently found these forums. I have C-spine issues as well as thoracic outlet. I had surgery for TOS several years ago and have done well. The 1st rib was very abnormal. Since the 1st rib resection, I've had several EMGs which all show nerve regrowth. I'm back to researching health issues as I am having nerve problems involving the same extremity again (different than before). C-spine has been ruled out. EMG this time around doesn't show TOS problems but this is the norm rather than the exception (my EMG pre-surgery was positive for TOS). Symptoms are different this time around but may be a combination of several problems in the vicinity. Doctors are stumped right now so I'm looking around . . .
