My experience is very similar to yours. I was diagnosed in late June 2024 with PMR and GCA. I started at 60 mg prednisone and stayed there for 6 weeks. I started weekly Actemra injections in August. I will step down to 7 mg prednisone tomorrow. My rheumatologist was a little conservative with my treatment because I had had vision problems from the GCA. I haven't had any problems so far. It sounds to me like your GCA is flaring. Could you get advice from a doctor about what dose of prednisone you should be taking?
