They ordered the biopsy and I did not have GCA. I was put on prednisone 20 mg and could feel it working within 6 hours. I could actually life my arms in the air and wave them around! Wow. All symptoms were gone within 48 hrs. It's been almost 3 years on prednisone now, a trial of methotrexate and now Kevzara. I couldn't get below 8 mg prednisone for a long time but now tapering and at 5.5., soon to 5.I have some bad days but am hiking, riding my bike, gardening, just less than before PMR. I feel pretty good and if the Kevzara just helps me go lower on the prednisone I'll be happy. I have minimal prednisone side effects, will wait to see what the Kevzara is doing to me when labs are done next month. Hope you are doing well!
