First off I'd make sure that your rheumie knows how you are feeling, as it sounds like maybe your treatment isn't working as well as it could. Also, if you are prescribed NSAIDs but have only been taking them "for pain", maybe you could take them regularly "for inflammation" until things calm down again. Single doses of NSAIDs aren't likely to do a lot, but you may find a couple of weeks on them does do something to break the cycle.
