When a pain management doctor won't treat your issues. Or rheumatologist.
Try another rheumatologist, if possible. Not all are equal....
I've had that done several times. When I had a good pain management doctor for injury at work. Also oxygen bed and chiropractic care. Water therapy. And now last 3 yrs. None of it covered by my insurance
Rheumatologist is your best choice. If your pain doctor does does Radiofrequency nerve ablations they help alot.
