Since a 2nd flare up recently of Polymyalgia, I am currently on 12.5 mg of Prednisone down from 15 mg which has significantly helped with pain everywhere except my lower back. I have had serious back issues which have always been managed with epidurals. As mentioned in an earlier posting, it is so difficult to tell the difference from lower back stenosis pain and PMR back pain. Has anyone had epidurals while on prednisone and are there additional risks?
