Dear Wildberry,
Here, in this forum, at this link (see below) are names of TOS doctors, Physical Therapists, etc., in Minnesota, etc., who know something about diagnosing and treating TOS, and/or diagnosing anything else you may have (along with TOS, or instead of TOS)!
Click on this link, and then scroll down to the Minnesota listings!:

Call them, and, read my message above, plus other folks' messages, for advice. Good luck! Don't give up!
Carol
