On a cruise at the beginning of April 2016 I got a sore right arm. I thought I had hurt my arm lifting my heavy suitcase. Five days before the end of the cruise my other arm hurt and my buttocks. My husband was helping me out of bed. When home my doctor did blood tests and diagnosed PMR. I guessed this myself as I have other auto imm. disorders. Doctor put me on 20mg of Pred. Miracle! my pains disappeared but I felt spaced out, exhausted and had a continuous headache. She gave me information to read about a plan we would undertake. I pointed out that the guidelines said you should start at 15 mg. She told me to come down to 15 immediately which I did three days ago. My pains have all returned and I still have the headache and the spaced out feeling. She is contacting me in a few days to see how I am. I feel a bit lost.
