My doctor told me yesterday that he doesn't think it's TOS because my CT, ultrasound, and EMG all came back negative. He said for me to do some research on my own and bring to him in 2 weeks and maybe we can figure out what's wrong with me. I already have a lot of TOS info and was wondering if anyone knows of any good web sites of conditions that are similar to TOS? BTW, 3 physical therapists think I have TOS despite what the doctor says. Also has anyone had much success with yoga? The doctor recommended that I try yoga classes 3-5 times a week and I'm just not convinced that's a good idea as I can only tolerate very minimal stretching at PT at this point.
