thank you so much for the reply. I have not had an xray or an mri. I did see a PT originally who said a pinched nerve in the neck. When I started having more circulation issues, I went to the Physiatrist (Sports Medicine MD), who suspected TOS. I have a $6k deductible so I was hoping to avoid a bunch of tests. The physiatrist doesn't want me to try any PT exercises until she sees where it is. I have less carpal tunnel systems than at first. Maybe it's time to try another DR--surely they can help with something w/o a test-?
