That's what I thought. I may try alternating every other day.

I have been on 5 mg of Prednisone for over 15 years treating for general arthritis. About a year ago I was diagnosed with PMR. I was initially treated with 20 mg and tapered down to 10 for several months, but had 3 flair ups so was placed on 20 mg of methotrexate. Like you , I thought the methotrexate wasn't doing anything. About 6 weeks in the methotrexate kicked in . I am now down to 9 mg of Prednisone over 4 months. I am almost pain free in my shoulders and legs and am back to playing pickleball 2 to 3 times a week. I am 74.
