I do emphasize with this roller coaster ride of PMR and prednisone. I Have been gradually weaning for the last six months and now down to 2 mg. I suddenly started having low back pain specifically in the sacroiliac joint area radiating down my leg. Typical SI symptoms. No other PMR symptoms but was initially concerned that it was a relapse. Doctor advised using Tylenol or ibuprofen and if that works then it probably isn’t PMR. Along with the appropriate stretching exercises and the Tylenol it works. Keep in mind that everyone is different and your rheumatologist knows you And the treatment plan that you should be on
