I was diagnosed with PMR in July 2024 and referred to a rheumatologist. I started on 15mg/day of prednisone which eliminated nearly all of my pain within a day or two. I tapered off at a rate of 5/mg the first month, and then 1mg/month for the following months. I experienced a flare at 4mg/day which resulted in returning to 10mg/day. I have been doing a very slow taper for more than a year and am currently at 1mg/day. I had been doing reasonably well at that level with some morning pain and stiffness that resolved by mid-day until about 3 weeks ago. While traveling I began experiencing pain in my sternum, ribs and difficulty taking in a deep breath without pain. After ruling out heart and similar issues, it was suggested that I may be experiencing costochronditis and should talk to my rheumatologist about that. I am now back in town and have an appointment tomorrow, and am interested in hearing from anyone who has experienced a similar issue. Thank you.
