Hey, Sylvie, I haven't heard of it - but, I'm gonna look it up.
Yes, I was in diagnosis limbo for YEARS.....I still don't get definite answers, but at least a handful of Rhuemy's believe I have 'something' - I know, does 'something' help? Not sure - but they argue which type of arthritis I have, at least that narrows it down a little - ha ha. At least I'm getting some relief from Plaquenil. I've been thru the whole gambit of RA drugs with no results. I'm getting ready to add (try) Arava to that list.
Elavil is not a steroid. If you do have a rheumatic disease of some kind, though, you might want to inquire about prednisone. I know that's the treatment of choice for PR (forget how to spell it:)). If you respond to prednisone, you definitely have something inflammatory going on. A co-worker of mine thought he had RA. Was dx with RA by first rheumy and put on mtx for 6 months. Did nothing for him. Went to another rheumy, was correctly dx with PR, put on prednisone, and it cleared up in a day or two. He stayed on low dose prednisone for a year (I know it's a long time), and he is not completely cured. If you haven't tried prednisone, ask your doctor about it. It's worth a shot anyway.
Elavil is not a steroid, it is medication to help you deal with the pain (pain management.) Depending on the dosage, it is given for pain management, depression, and possibly OCD and panic attacks (though, that might be Paxil only....I switched to that after a year on Elavil, it was making me too tired) It did help me a lot, I was able to deal with the pain a lot better after I started it.
I hope you are starting to feel better.
