Hydroxychloroquine S/E flushing skin?
Based on my list of of symptoms, a rheumatologist believes I have Sjogren's and possibly a lupus antibody, although all my blood work is negative. I started on hydroxychloroquine about 2 weeks ago. Since then I have experienced intestinal upset, itchy torso, thirst, anxiety and disturbed sleep with strange dreams. I was tempted to bail on this med, but my rheumy urged not to and reduced my dose from 400 mg to 200 mg daily. One new symptom that concerns me, because I don't find it in S/E listings, is flushing around my knees after showering and flushing of my hands, both sides, in various situations, such as with a temperature change, anxiety, possibly florescent light and/or sun exposure... I do have some intermittent hand pain with this, but not exactly in the joints. It's along the bones between the joints, maybe bone, maybe muscle or soft tissue. It's hard to tell. Maybe it's pain radiating from the joints, which are not stiff in the morning. The Rheumy doesn't believe I have RA. I've read RA can cause palm-side redness.
So, my main question, can hydroxychloroquine be causing flushing of the top of my hands as well as palm side (and my inner knees)? Or, is this just Sjogren's/autoimmunity?
