Hello @carol75, 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.

It's good that you have an appointment scheduled with a rheumatologist. The tenderness in the temple area is a sign of Giant Cell Arteritis and much more serious that PMR. How soon is your appointment? Can you share an update with us after the appointment with the rheumatologist?
