Hello @lisaparisella, Welcome to Connect. I'm sorry to hear you haven't been able to find a treatment other than prednisone. There are a couple of discussions on the topic that might be helpful:
--- PMR: Are there treatment alternatives to Prednisone?: https://connect.mayoclinic.org/discussion/alternatives-to-prednisone/
--- Alternative to Prednisone for Treating PMR?: https://connect.mayoclinic.org/discussion/alternative-to-prednisone/.

Have you seen a rheumatologist to discuss alternative treatments?
