Checker is right. research the doctor who will be doing the surgery. I do not know about TOS, but the folks here sure have experienced a lot of pain with that after surgery.
I had C3-7 done, my second fusion. It was very very painful for me. In fact I refused to go home from the hospital! They wanted me discharged and the pain was not in control, so I stayed. It took me, about two weeks to start to feel some relief. Nerve pain was gone, but the surgery itself was an OUCH!!!!! Not everybody has such painful experiences with these surgeries, each of us is unique in how we respond to it. I wish you all the best Logan. ginnie
