I resolve to better my understanding of PMRGCA flares vs. prednisone side effects. I started on 60mg. In May 2016 and had tapered to 30 in three months. I developed a flare or side effect, don't know which. My RA put me back on 60mgs. prednisone. It's been 5mos now and I'll be back to 30mgs. Jan. 3rd. My daughter wants me to tough it out and continue tapering. I don't want to miss signs of a flare. How often can you have ESR and CPR blood tests? Is that the definitive test for a flare? If so, why not inflammation blood tests more frequently?
