I am 72. My PMR turned into Rheumatoid Arthritis.
Two months after I went off the PMR, my C Reactive Protein went up again and my rheumatologist sent me to Vancouver to get a special scan of my blood vessels.
The rheumotologist said he thought it was rheumatoid arthritis. All the scan showed was that I had some inflammation.
I started on Methotrexate. It has reduced the swelling around my joints and I can walk better. It also took care of a rash I had which was in the end was psoriasis.
My problem is that with all that has happened, it has affected my emotional well being. I am not motivated to do anything the last months.
I have been in a 12 Step fellowship for 24 years.
I have a Higher Power and I do believe that things happen “for us and not to us.”
I live alone. I am on a fixed income because of my divorce as he lied and stole.
I still do everything for my program every day. It’s just the joy is gone.

This would make me suspect psoriatic arthritis.

"The most commonly used disease-modifying antirheumatic drug (DMARD) is methotrexate (Trexall, Otrexup, others)."

I don't think PMR can turn into Rheumatoid Arthritis or any other type of inflammatory arthritis. Sometimes PMR is misdiagnosed in the beginning. The other likely thing that happens is you may have PMR in addition to inflammmatory arthritis.
