Beverly -I pretty much agree about not having another surgery so soon.
You need some decent pain control for starters - so you can think over your options and the pros and cons of another surgery.

SeaPines makes some good points about those doctors possibly taking the long route to finding the real problem for you. Are they all in the same area, office, hospital or friends?
Perhaps a second opinion from an outside doctor?

The risks of more surgeries are possible scar tissue problems and a possibility of RSD.

Some thoughts-
do you think you had TOS before all of those surgeries?
OR could any of those other surgeries caused TOS or aggravated your TOS?

Pain management-
yes - your pain is not being controlled at all - that is the # 1 thing they need to do for you right now - so you can step back and really think about the surgery options- pros and cons.
