Nina 987- I'm in SD and my therapist has worked with TOS patients without surgery, and like me following surgery. UCSD is a fantastic facility. Send me a note if you want more info. Having VTOS I completely understand your fears. I also had blood clots in my subclavian vein. My case did not allow the option to forgo surgery. Ive been highly impressed with my therapist and surgeon though. I have been blessed with them though this mess.
