I can't give a place to find info, but I suffer from both illnesses. As a matter of fact, I've often wondered if there is a place for FM after the name change to ME. We're definitely stepchildren.
There is a lot of pain involved with FM. I've had it for probably 40 years now, and it changes form and you do learn different methods of treating it (plus you just know you're never going to be even close to pain free). I find that the drug lyrica helps with pain, ice pads definitely help me more than heat....will numb the pain entirely, especially if I lay directly on the spine. I also use it on the neck and shoulder areas and anywhere else that needs it. (I use Ace ice packs....different sizes & reusable).
There are also creams that can be obtained (with a prescription) from Compound Pharmacies. Heat is the enemy of these creams, so make sure it's well packed in ice.
Also, I've noticed a lot of over the counter products that are containing 4% lidocaine.....really, it's a combo of many things. If I get it under control, it generally works for at least one-two days, sometimes longer.
We're not all the same, so the body doesn't respond to all treatments in the same manner. Still, some of this may help you.....I hope so.
I used the exact same treatments when I fractured my pelvis in a number of places going on 2 years ago. Also my fractured vertebra. Since the med profession can't give you anything that erases the pain, I used the above and wasn't in non-ending pain. I just had to be on top of it. The injuries were bad enough that I was bedridden for a year, couldn't walk and even now things aren't right. Well, then I was told to expect arthritis within 5 years.....I have osteoporosis and have already lost 3". I had osteoporosis when I was 40 and no, things like Fosamax, Prolia, etc., don't necessarily work. Good luck to you. Yours, Lenora
