Hello @norieaugustine, Welcome to Connect. I have PMR which is currently in remission but when it was active my primary care doctor along with my rheumatologist would frequently ask me if I had any pain in my scalp or temple areas which can be an indication of giant cell arteritis (GCA). I also lived with some pain as I was tapering off of prednisone for both occurrences I had with PMR. My rheumatologist had me keep a daily pain log along with the prednisone dosage I was taking for that day which was helpful when I was tapering off of prednisone. Here's some information on GCA that might explain it a little better.

Can you share a little more about your PMR diagnosis and how long you have been on prednisone?
