Just want to extend a warm welcome!

It looks as though you've already been given excellent advice. Off the top of my head, not sure I have lots to add, except that maybe the xray would be in order to rule out cervical ribs? (Then again, maybe not absolutely necessary if you were to get a definitive scalene block....I guess Dr. Jordan or whoever could make that judgment.)

If it turns out you can't afford PT, maybe another possibility would be Sharon Butler's downloadable (Hellerwork) thoracic outlet self-care program. I think it's only $29:

Had to smile/nod my head at your description of the "uninterested, detached" doc....Heck, I think I've seen that guy myself. Seriously, I think many of us had had similar experiences.

Best of luck, and keep us posted.
