@ceedub If you have an AI tool, you might ask it the question about reliability while on prednisone and GCA symptoms. I believe that both doctors could be correct because one is looking solely at potential eye damage and the other is looking much more holistically at overall symptoms returning. Just because doctors don't agree does not make one right and the other view point wrong.
I have had totally asymptomatic GCA for several years that went undiagnosed and has done vascular damage, not eye damage because I have never had a cranial symptom. Plus my eye doctor examined me annually and looked for signs of GCA. It was silently doing damage elsewhere.
I am telling you this mainly so you realize that there are patients outside the fat area of the bell curve and from time to time it could be you. Doctors look mainly at the fat area because that's where most of us are most of the time.
