Did you find our Drs & PTs sticky thread?

Or post your area so members can suggest any TOS drs nearby.

If no TOS specialists are close perhaps seek out a savvy expert PT for a full evaluation.
You can call various PT places or possible even chiropractors and ask them if the have treated TOS/thoracic outlet syndrome, but they may just say yes, or they may say what ???

Some only slightly know about it and no set PT plan fits for us, treatment has to be personal and case by case..and adjusted as it goes along.. no quick fixes usually.
A chiro may be good to check with also, if there's possibility that misalignments
could be a factor. Whiplash, sports hits, falls, accidents...etc.

Also posture should be addressed, shoulders and head aligned with hips and knees when looking from the side..
