Latest news. I started actemra for inflammatory arthritis. Im tapering off prednisone and now at 12.5 mg. No pain at all for the past month. Im hoping for a quicker taper. Also, the rheumatologist is syltill worried about giant cell arteritis (gca). I have absolutely no symptoms except my age. And that i had 3 m8graines in a row 2 months ago. I get occasional migraines, so the only possibly unusual thing was 3 of them. None since. Im pretty positive I don't have gca. It's inflammatory arthritis.
