I was diagnosed with GCA in November 2024. As soon as myMD/PCP realized what my symptoms (which did include all that you mention plus some loss of vision in my right eye) indicated, she sent me for lab reports to check on inflammation, gave me a shot of prednisone (don't know the amount) and prescribed prednisone at 60 mg per day to protect my eyes. She also contacted a vascular surgeon for the needed biopsies. Only then did we discuss finding a rheumatologist. The prednisone immediately took care of my symptoms. I saw a rheumatologist a few weeks later and he picked it up from there. So, I think getting back to your PCP immediately would help. It is all about protecting your eyesight. I am 82 years old and successfully tapered off the prednisone and have been on Actemra ever since without problem. Best wishes. It's a difficult journey but not too bad. No one in my Northern European family had this either. Just lucky, I guess.
