Pokejedi9814, you ask a good question! I can't really say if you are dealing with RA related swelling or not, as I can't provide medical input and I also don't know what your knees normally look like. That said, I know the wait for an appointment when you are hurting and anxious can seem endless! How soon is your appointment? Does anything help when you are hurting (ibuprofen, heating pads, ice packs, etc)? Swelling and painful nodules can occur with RA, and your physician should be able to help you get to the bottom of what is going on and (hopefully!) offer some viable treatment options. I hope you get some relief from the pain very soon! Keep us posted on how that appointment goes, if you feel comfortable doing so. Best, Erin, RheumatoidArthritis.net Team Member.
