I had a telemedicine visit with my rheumatologist today. Since I've shared my history and asked for advice here in the recent past, I thought I'd share how it went.
The visit went almost a half hour (one of the things I like about my rheumatologist is that he doesn't try to rush my visits). I shared with him what I've learned from this forum, and he is ok with the "slow taper and go back to a previous level if needed" advice I've learned here. If he had opposed it, I was going to look for a second opinion, but since he is amenable to the approach, I thought it was valuable to have a local rather than a distant rheumy.
After discussing options, he felt that, since my major symptoms are those of PMR, not the psoriatic arthritis flares of the past, I should go back to being treated with prednisone. What makes my case a bit different than just PMR alone is that my RF and CCP values are elevated, indicating RA, yet I don't have any joint or limb involvement (my pain and stiffness are all located hips to shoulder). The RA markers and the psoriatic symptoms in the past was why he had proposed MTX.
I go back on prednisone tomorrow (10mg/day, since I was symptom free at that level) and will see him again in six weeks. No tapering until we meet again. I should call him if I have any significant changes before then.
