aewin, I see this was posted 2.5 yrs ago. I would be interested to know how it all came out. I was diagnosed with PMR Oct. 2025 after 4 months of unexplaiable debilitating pain and soreness. I was warned, early on, to look out for GCA symptoms as this can result in strokes and blindness. I developed unusual GCA symptoms Jan 2026. Nightly jaw pain 8/10, soreness at temples and posterior base of my skull. Jaw claudication with chewing firm foods, but no headaches. My PCP didn't pay much attention because it wasn't the classic symptoms. My research revealed that I was, in fact, having GCA symtoms. After 5-6 weeks I convinced my PCP. The temporal artery boipsy confirmed the diagnosis. My wonderful rheumy with decades of experience is Hungarian. She is fabulous. She consulted with my PCP and insisted on the surgery.
I pray you found a knowledgeable rheumy and received a definitive diagnosis without any permanent damages.
