Is it really PMR if symptoms aren't upon awakening?

I have been following multiple groups including this one to see if anyone's experience is similar to mine. I have the classic PMR symptoms (hip, thigh, shoulder and upper back ache, fatigue and weakness)except that I wake up feeling fairly pain-free in the morning. Then as I go about my day and start to get active the pain comes on with the fatigue. Rest and over the counter pain meds seem to help. I do get the stiffness in those same places after brief rest and when I'm trying to get up. My lab work shows some inflammation. I have two other autoimmune diseases, Vitiligo and alopecia areata. It's so confusing to me that I don't have the worst of my symptoms when I wake up. I wonder if there's anyone else out there that has a similar experience or am I misdiagnosed? I do see a rheumatologist and I was diagnosed after finding relief with prednisone. I ended up being on it for 9 months and slow tapering off and within a week my symptoms came back. Now she wants to start me on kevzara.
