I do not believe I have met you before so hello and welcome to Helaing Well's chronic pain forum. I can pretty much tell from your post you feel you are at the end of the road on getting help or relief with that shoulder. It is understandable it has been going on a long time.
You asked what a pain mgt dr could do for you. Well, there are alot of different things that can be tried to try and get your pain reduced. But first, you need to know there are two types of pain mgt drs. One kind will do injections and different procedures only, no medications at all. The other kind will do the same except he will write scripts for medications that he feels may help you. If you have access to the drs lists online at your insurance company, then I suggest lookingt there to see who is on your list. Also, most all pain mgt drs want patients referred to them by another dr. This can be a primary care physician or even a specialist making the referral. Next I would call and make sure they are still on your plan (sometimes they are not but have been taken off the list), make sure they are taking new patients, ask if a referral is needed and then ask if the dr writes scripts if he feels the patient needs it. This will not make you look like a drug seeker when asking this question. The main thing is to put together a plan to help you get to feeling better and be more active and have more quality life.
Pain mgt drs are more in tune with the pain medications available on the market today over our primary care drs or specialists. Those guys normally do not like to write pain meds for more than a week to ten days. A vast majority of pain mgt drs requires the patient to sign what is called a Contract. This Contract pretty much lists all the do's and the don'ts. If a patient slips up and does the don't, many times they get kicked to the curb then no other pain mgt dr will see a patient. It will be put in your medical records and those follow to around from dr to dr. Normally we can get pain meds from the pain mgt dr only, use one pharmacy to fill rx's, no dr shopping, bring bottles in for pill counts, do random urine tests to make sure the patient is taking their medication and not selling it. Also, if the medication is not taking as prescribed and you run short this can send up a red flag to the dr and create all sorts of probllems, including having to find a new dr. There is more but this gives you a general idea how it works. Never ask a dr for a specific medication by name, instead write down what meds you have taken and how you reacted, if helped or did not help. Since you have had surgery on your shoulder I would stay away from chiropractor care, because of the type of surgery you had on the shoulder. I am not so sure I would want a chiro popping around a shoulder like that, not after having surgery on it. I am not anti-chiropractor either. I do believe they have their place in the medical community.
I hope I have helped you a little here. If you have more questions by all means ask them. People are usually in & out of here at all hours of day and night. Good luck and let us know how things are going.
