Hi, I've been lurking here for a couple of months. I'm currently on the NHS merry-go-round trying to get some kind of diagnosis. Had a few joint twinges here and there, stiff feet in the morning for a couple of years now, but suddenly developed very painful joints (knees, hip, hands/wrist/elbow) following a bad cold in November. Doctor currently has me on Naproxen with Lansoprazole to protect my tummy, but now my feet and ankles are swollen but not painful. I've never had this before, not even when pregnant so was wondering if anyone else has had this happen when taking these meds?
