Hi @SusanEllen66, Here's some info on Erythrocyte Sedimentation Rate (ESR)...

"Based on Mayo Clinic clinical laboratory reporting, an ESR value of ≤22 mm/hour in men or ≤29 mm/hour in women was considered normal regardless of age. A normal CRP was defined as a value of ≤8 mg/L in all patients regardless of age."

ESR indicates inflammation in the body. So does CRP.
ESR is your sedimentation rate. Google it. Should have been done immediately. Actemra is drug used with or without prednisone to bring down inflammation. That’s the brand name. Made by Astra Zeneca. Google Actemra. It is a biological. You need to read about this drug and GCA. You need to read about trials and new drugs for autoimmune diseases.
