How can i bee in so much pain and have every test done and normal but my pain is so chronic daily pain in left side chest and sholder blade help ?

Pain syndrome: Negative tests must be acknowledged as usually a good thing, since they look for "bad" conditions. Does not mean you don't have pain. If badness ruled out, consult a pain management specialist for adjunct medications / procedures to reduce pain.

Muscle Spasm: Sounds like you have an internal muscle spasm. Best person to treat this is a doctor of osteopath that is trained in manual manipulations. Sometimes you may find a physical therapist with advanced training in these osteopathic techniques.
