I don't have erose arthritis per se, but from the description it sounds very much like the effects of RA contained mainly to the fingers and hand, which I do have. My fingers and hands, and especially wrists, have been aggressively targeted by my RA for years and I can tell you that it is definitely painful, especially for a career in writing. I try my best to use the over-the-counter NSAID gel and alternating heat and cold, depending on the situation. The same holds true for my foot and ankle, when they are bad and, like you said, sometimes there is just no substitute for resting and/or sleeping until the next day when everything tends to "reset" and we start once again! If it is indeed erosive arthritis, which is a form of osteoarthritis, it is not surprising the RA meds don't help as those are meant to target the immune system parts which cause RA, and that's not the cause of OA, which, unfortunately, doesn't have a "cure" as it is basically from years of wear and tear. I think you are probably doing everything you can if it in indeed OA that is the main cause of pain and damage. I know that's disappointing, but if you need anything, we are here to help. Keep on keepin' on, DPM
