They have alot to offer but will try and keep drugs to a minimum based on your pain levels....they do blocks, epidurals, PT, drugs, just about everything while trying to rule out over doing it with just meds....they seem to try and get right down to the pain indicator and address it....as with any doctor you can get a good one or a bad one......if you in fact do have a herniation then you need to try and rule out ALL other methods to relieve pain before looking into surgery......in my opinion it helps very few with herniations but it needs to be tried as surgery is not always the answer either and some will do good with it.
Oklahoma has some very good PM doctors but I do know of two that I would stay away from......what part of the state are you in?
I wish you the best of luck!
