I have been on Hydroxychloroquine for a few years 400mg daily and reduced down to 200mg 2 months ago ( my request) and on weekly Benepali injections for 11months. RA now under control and felt best ever. Had two finger joint cortisone injections recently ( second worked). This weekend have experienced very severe dizziness, random headaches coming and going ranging from elastic band round head feeling to head feeling full, very nauseous feeling / churning stomach. Recall I had a slight version of this few weeks ago for a day. Has anybody experienced similar?
