Thank you. So the breathing exercises stopped the shoulder pain as well? Can you detail which stretches or shoulder exercises you did, or was it the breathing alone? Seems a ton of time commitment, many hours a day!!

In my case, I think my left side deep neck flexors are all messed up, and right are weak. Left worse than right. So right side scalenes are overactive. It seems to be some sort of paradoxical CNS response post whiplash to protect the left side. That right side spasm or the whiplash shut off my shoulder muscles as well. Its a pain to work through all this, and the subtle arts, ie breathing, isolated muscle activation seem to be beyond me.
