I was treated for GCA in 2019. My symptoms started across my facial bones near my eyes and in left temple. I saw my ENT thinking it was bad sinuses. He sent me immediately for labs. The labs were normal. He recommended seeing my dentist and opthamologist. Dentist sent me to Endodontist for extensive scans and test which were all negative. Opthamologist visit showed nothing in eyes But he wanted to treat it as GCA out of caution of sudden temporary or permanent blindness in eye near temple pain. He told me the only definitive test is temple biopsy looking for giant cells. However unreliable as the artery inflammation leaves gaps and biopsy could miss. I drove 300 miles to have a duplex ultrasound that diagnosed possible GCA. My Rheumatologist told me if GCA that my jaws would hurt and would become very weak and heavy when chewing food. My opthamologist was not as passive so he started me on 60mg of "nightmarish" prednisone. Tapered to 5mg over 6mos then possible flare so up to 80mg ordered by now new doctor(Neuro opthamologist). Finally off after one year. This was five years ago and still suffer from side effects of Prednisone. Unfortunately, I'm now having PMR symptoms in hips, shoulders and knees. I Do Not Want to Take Prednisone due to all the damage it caused. The sad part for me was within a month off prednisone taken to protect my sight I developed a hole in Macular. Surgery did not correct my vision.
