I have polymyalgia rheumatic and have been on prednsone since last June. My dr has me down to 12 1/2 mgs. for another 2 days and then she wants me down to 10 mgs. I don't like the way prednisone makes me feel, I am jittery, feel tired, a strange, tired feeling in my legs , feel sleepy, etc. The inflammation level is down to normal. How much longer must I stay on prednisone?
