I have had PMR /GCA for 10 months, symptoms stable. I have been reducing from 40 mg to 12.5 I have just reduced again to 10 mg 6 days ago. I have been getting neck shoulder and hip pain for the last 3 days, how do I know if this is the illness coming back or withdrawal from prednisolone? I have started back on 12.5 because of the GCA. how long could I have left it before I went back to the higher dose?
