kevzara and relapse

I started taking prednisone in October 2024 for pmr. My rheumatologist started me on kevzara the last week of December and it has been a miracle drug. I was able to reduce prednisone from 13 mg to 4 mg very quickly. I then started a slow taper, .5 mg per month and was able to get as low as 1.5 mg. Unfortunately, the pmr symptoms (extreme fatigue and shoulder pain) returned about 5 days ago. I upped the prednisone .5 mg to 2.0, but still no relief. Has anyone else had a similar experience with Kevzara? If so, would you please share how - or if- you have resolved the problem?
