Hello,
There is success with surgery for TOS but proceed with caution. Not all people with TOS need surgery PT has come a long way in helping with opening the bracial plexus area up for relief of pain and function. I was the never before seen case with ribs out my C7 L and R sides also subclavian artery entrapment L more than R but yet again both sides. Bracial nerve bundle damage, had repair and band removal on both sides also major muscle damage with scared muscle and cervical rib puncture through right side bracial plexus nerve bundle down to right lung, that was disected also. It all works now I'm careful what I do but without the surgery I was close to no use of my arms at all. Any questions?
