My pain doc calls himself a physiatrist. He has a pain and rehab office specializing in non-surgical diagnosis and treatment of pain from injury, etc. He does electro-diagnosis (nerve conduction and such), spinal injections, and refers for PT. Rehabilitation and physical medicine is a board certified specialty.
I especially like that this doctor treats the whole person, not just a little piece of me. He's had me try all sorts of meds for fibromyalgia, which unfortunately haven't helped. He was the only doc who believed I really had pain in my shoulder, ordered an MRI which showed bursitis and tendonitis, and gave me a cortisone injection which helped a lot. I still have a little arthritis, maybe something else going on there, but the upper extremity orthopedic specialist kicked me to the curb saying it was just my fibromyalgia.
Funny, not really, how once you get a diagnosis of fibromyalgia every pain gets categorized as "just your fibromyalgia," and dismissed.
It's not the same as going to a rheumatologist, a good one that is. Rheumys should be able to diagnose fibromyalgia, eliminate other possible diagnoses by ordering specific blood tests, more expertly. It takes a bit of time to push all those pain points, and most PCPs, orthopedists, other docs only give a cursory poke which is not enough.
The other option for spinal problems is a spinal surgeon. They aren't interested unless there is something surgical, but they may order an MRI to check that out.
