I was diagnosed with PMR about two years ago. I was dealing with extreme discomfort in my upper torso and upper legs. My family practice doctor ordered a blood test which indicated a very high CRP level (.80). He prescribed prednisone (20mg daily), and I experienced almost immediate relief from the discomfort. Because of my favorable reaction to prednisone, he determined it was PMR. I then went on a 10 month prednisone taper. I was also diagnosed with GCA about year ago and I am currently receiving monthly infusions of Actemra.
