I have no idea if it’s even possible, but I believe I had PMR initially and it evolved into RA. In 2012 I had an onset that took me from absolutely normal when I went to bed to numb/weak hands the next morning and within 3 days all the big joints were involved - shoulders, hips, ankles, feet - and hands. It was gruesome. I found a great Rheumy (after one not so good one). I was sero negative. But Humira and Methotrexate was a miracle. Until I had to reduce methotrexate so low I wasn’t protected from developing antibodies to Humira. Switched to Enbrel since it doesn’t trigger antibodies. It worked - until it didn’t.

Skip to 2019. Moved to NC and the first Rheumy told me I had Osteo not RA. Blood test for RA FACTOR WAS… positive!! So I had changed since onset. Immediately found another Rheumy since that one was stupid.

I’ve been on Remicade infusions for 3 years or so. So far so good. Praying it lasts. I still flare -which happened after my recent lung surgery. But even that was a blessing because the Prednisone I received confirmed my rib and diaphragm pain was ‘only’ inflammation.

Anyway - I think because of big joint onset and small joints for the duration - plus sero negative then positive, that maybe I’ve had both PMR and RA. Not that it really matters.

Thoughts?
