From 10 to 5, I tapered at 1 per month. Most random discomforts were during this period.
From 5 to zero, at 0.5 per month. Very few incidents of random pain.
Below 10, never tempted to delay the taper or increase the dose. Tylenol, an an occasional 125 Ibuprofen (once I was below 3, and wirh docs agreement/permission) worked for me.
If possible, try to not start chasing random pains with varying doses of prednisone.
Good luck. Some is needed.
