I'm nearly two months in, trying to fine tune my Prednisone dose. The rheumy prescribed 10mg, and I was hovering between there and 15 (which is a common starting dose). I just keep having achy legs and feet, day and night. The Prednisone, at either 12.5 or 15, is doing a good job of taking care of all my old PMR symptoms, with just minor bursitis in the elbows and shoulders. I can function really well, and think I could easily taper the pred down, but the aching pain in my legs (mainly calfs and feet), both day and night, concerns me. Two months ago I had only slight pain in my calfs and none in my feet, but now pain from my knees to my feet is my most noticeable issue. Do you think this is just a side effect of taking Prednisone for 2 months?
