Hello there. I would get an appt with your Dr and have it checked out. Are you having just the pain in the wrist? I know when my Still's is flaring up my bony parts of my wrists and knuckles are so swollen I can't see them. There could be a cyst there or arthritis but it is hard to say, there are over 100 different kinds of arthritis. I would definately give your Dr a call.
