You're correct about what a pain management specialist does. They look at the reasons for your pain and try to come-up with the most appropriate plan to treat it effectively. The goal, because of the likelihood of addiction, is generally to do so with as few medications as possible.
The suggestion about acupuncture is a good one. I wanted to try it during chemo to help manage my nausea, and my insurance was willing to cover it. I couldn't find anyone within 50 miles of Indianapolis that participated with acupuncture as a primary specialty.
Good luck - I hope you find relief soon!
