Is it PMR (and/) or Osteoarthritis?

My encounter with PMR began in November 2022, when suddenly I was beset with the pain and stiffness you are all familiar with. Even rolling over in bed required a fully-developed plan implemented with gritted teeth. Climbing the stairs was done on all fours. After a couple of weeks the diagnosis was made and a hefty dose of prednisone was started. This med was almost cartoonishly effective. Now I am on a taper like everybody else here!
Anyway, for months I have been bumping my way down the taper (presently a split dose of 6 and 3), with a pain level of 1 to 1.5 fairly consistent, and with a rare 2 or 2.5 usually associated with strenuous labor. However, ever since beginning the prednisone I have had no symptoms in my upper body; they are all located in the hip area. Furthermore, the symptoms are all located in the groin area, say, inboard of the hip flexors. OK, near my tackle. I have zero symptoms outside the groin area.
I know that osteoarthritis is lurking as it was identified in a hip x-ray taken when this all first hit, but the arthritis had been asymptomatic. But I am wondering now if in fact the PMR is being fully controlled by the steroid and all felt pain is actually associated with the arthritis. If so, perhaps I should stop hand-splitting firewood and speed up the taper.
Could you please weigh in on the following questions?
1. Do you have symptoms in your upper body/shoulders?
2. Precisely where are your middle-of-body symptoms located?

Many, many thanks!
