I know where that is!

True that the disc disease wold affect those areas but the tight mucles make it worse.

Ultrasound is a kind of deep heat treatment for the muscles and the joints. Gets blood flowing to all those areas that are tihht and not moving.

Ask your PT is she can do ultrasound on your T1-t4 areas.

Cranial sacral massage helps too. And its very gentle. Also look for a feldenkrais practitioner.

Many of us have not had good experiences with PTs that no experience with TOS. They will make it worse.
