Prednisone Taper Stories

I will be under the guidance of Rheumo to taper Prednisone which is presently 14 mg down from 15 mg. We tried the fast track of 12.5 mg x 3 days, then 10 mg. Symptoms returned. Tight glutes, pain down back of thighs and behind knees along with several hours of morning stiffness and limited mobility. I'd really like to get an idea from those who have successfully tapered if the goal is to be pain-free as opposed to a manageable level of pain or maybe somewhere in between? I'm 73 and I do not have a history of pain or mobility issues. And I was pretty limber. It's new to me to have to struggle to bend to pick up something off the floor. I do have a fair amount of pain at night while trying to sleep, mainly in one hip. And it seems that PMR has heightened my existing neuropathy symptoms.
I will say that none of this is as bad as it was when I went to my PCP for help. I'd appreciate hearing your stories.
