I've been away from the PMR forum world for some time, having learned to manage my condition more easily over the years.
I had worked my way down to a very low prednisone dosage requirement, which always fluctuated seasonally but which I got down to 1/2mg/day for some weeks last winter (but then needed up to 2.5mg/day this past summer).
This winter, I had several dentistry appointments in January during "peak COVID" times, so I had stopped taking prednisone (dropped from 1/2mg to 0mg) in the hopes of boosting my immune response.
Well it seems that at such a busy time for me that I then forgot to resume taking the prednisone, and did not see a significant recurrence of the typical arthritic ( mainly bursitis) issues that I might have expected.
However, my weight dropped from an already-low 138lbs to 127lbs, which alarmed me as this occurred within just two weeks time. So, in response, I continued my active lifestyle but began eating more often (and have by now returned to a higher 135lbs after 4 weeks). Presumably this modest weight rebound is because my "tolerance" for the prednisone had somewhat worn off over that period of weeks as my body's steroidal balance found a new equilibrium.
So here I am now at zero prednisone and 135lbs, and having noticed that increasing my weight upwards from 135lbs at this point seems to bring on hints of my earlier PMR symptoms (occasional ear ache, stiffer fingers/joints and fatigue).
That's about it for now. I am passing on my optimism, and will be reporting back on any significant changes (I do expect to be able to gain back some more pounds over the long term, just hoping not to need to go back to taking pred).
If/as any symptoms recur, I will firstly be trying to lose a couple of pounds (if the symptoms don't force the issue by themselves). I have become a believer in a strong correlation between weight gain/loss and the resulting affect on one's prednisone dosage requirement, which I feel has troubling implications with respect to one becoming more dependent on prednisone (with it's seemingly inevitable weight gaining tendencies).
