He said that because I have severe TOS and although a lot of people get some short term relief he said that in my case he doesn't believe it will help but may make it worse. And thats based on years of experience operating on people with TOS. For me the risks are too high so I accept that.

No not veryone benifits from surgery. From what I have read there are some horror stories from people and I don't want to be another one. Most people find that the surgery is short term and symtoms come back. This Surgeon is one of the best here so I can trust he knows what he is talking about and I trust his opinion. My GP wouldn't have sent me to him unless he knew his stuff so to speak. It's not worth the risk of Dr shopping and ending up worse off which is what he said to me.

I also have a genetic blood clotting condition which is affected by the TOS that I didn't know about until my 1st blood clot 2 years ago.
