@laura1970 I was doing so well tapering. Just prior to getting PMR I had terrible pain from a torn meniscus. It was treated with a cortisone shot. Soon after I developed PMR and started at 20mg/day. Very soon after taking my new steroids, my knee pain disappeared. I did very well tapering to 2mg/day. I am using methylprednisolone instead of prednisone and the pill only comes in 4 mg. I can slice it down to 1 mg. So to go down from 2mg to 1.5 mg I alternated days of 2mg, 1mg, 2mg,1mg, etc. I did OK for about 10 days when my knee pain came soaring back and PMR symptoms were starting in my neck and upper arms. I believe like you, my knee was causing adrenal insufficiency. I called my Rheumatologist and she agreed that I should stay on 2 mg daily for now. My PMR symptoms have disappeared. On Jan. 2, I will see an orthopedic Dr for my knee.
