I would definitely go by how you feel and how your symptoms are , if you are functioning well enough and PT is helping stick with it.

I think quite a few people get by with TOS, my pulse still cuts off in certain positions but I can handle that & adjust to it, and haven't had any clots or vascular problems at all.

If you don't have a lot of swelling, clots, or pain issues why have surgery....

Sometimes surgeons just like to do surgery....and make $$$
