Since I had surgery 20 years ago(scalenectomy) on my right side it's always been worse and more painful than the non surgery side. However, lately I've been noticing that the two sides are getting more evenly matched. In fact, during this last flare up that I've had there's been more pain in the nonsurgical arm than the surgical one. Also, I've noticed that I now have better flexibility on the surgical side than the nonsurgical side. So what does this mean? Could it be possible that the surgery I had 20 years ago did me some good but I just never had the proper therapy to release all the adhesions? I did work that way for more than 10 years before I was ever diagnosed with TOS and had the surgery. I don't know but this is getting pretty interesting. I just plan to keep on stretching and see what happens.
