I am a 24 year old band teacher diagnosed with TOS back in February. My symptoms began as right wrist pain about 4 years ago and since then have spread to many more. I have been to several docs and am in my 2nd round of PT right now. I am scheduled for surgery in less than 2 weeks now with Dr. Sanders. He's currently planning on doing a bilateral pec minor release. Recently after stretching my pec muscles I get this burning sensation around my collarbone....like a sunburn feeling. Is that common with TOS/pec minor syndrome or do I need to begin investigating RSD?
