I have dx of post lymphoma, lupus, sjorgrens, osteoarthritis, gerd, and others. Sjorgrens has been bad lately with everything thats supposed to be moist dry and lots of joint pain and general yucks. Currently on plaquenil and steroids for the lupus and sjorgrens. Dr thinks its time to try rituxan. Side effects are awful and I can not decide. Anyone out there been on this med?
