I would proceed since there is a danger of nerve damage each time you dislocate. I have had constant pain in left scapula area for 15 years. Doctors have not been able to do anything about the pain. One specialist suggested that surgery to scrape the bottom off the scapula would help. That seems quite drastic when no one knows what is really causing the pain.
Stress makes the pain worse.
It feels like a throbbing knot of muscle that is only relieved with pressure on the spot. A Cortizone shot to the area didn't relieve the pain. Acupuncture might be of help and would not be particularly invasive. Also, the surgical approach, if acupuncture does not work, is not reversible. I would see and osteopathic physician at least once.
