I am 74 years old and was diagnosed with PMR 6 years ago.
I was initially put on 15 mg prednisone daily and within 6 hours I was almost pain free. After a couple weeks I went to 10 mg a day and then decreased my dose by 1 mg every month until I was at 0. I also took Fosamax for a few months to prevent bone loss. I am now considered “cured” after being pain free with no symptoms and normal blood work for over 5 years. I had no side effects from the prednisone except having extra energy - it was a wonder drug for me.
I believe my PMR was triggered by emotional and physical stress. I had knee replacement surgery after which my mother became extremely ill so I had to deal with my physical recovery at the same time I was traveling back and forth to another state to care for my mother. Wishing you a speedy recovery.
