Re: Referred pain?
I think a good Pain Management doctor may be able to help you. They will usually want to see recent specialist notes and MRI's, etc. I have been with my PM for 18 months and I go once a month to discuss pain, get refills, etc. They also do Epidural Steroid Injections. I've also heard of PM docs doing lysis of adhesions (scar tissue) or referring the patient to someone that does.
Primary Care Physicians are most often not comfortable with pain beyond the simple cases where 1-2 months of medications help someone recover from an injury or illness. Even my Orthopedic Spine Surgeon was relieved (visibly, I could see it in his face) when I told him that as of 3 weeks post op I was going to go back to PM for further pain meds.
If you haven't seen an Orthopedic Spine Surgeon lately (or Neurosurgeon if you prefer) then that may be the first step to get a full evaluation. And if he/she has no treatment recommendations they can provide then you can say "perhaps structured Pain Management is what I need, can you provide me a few names of pain management practices you recommend?"
