@leon1649 - FWIW, symptoms began spring of 2022, diagnosed in the fall of that year and starting dose of Pred. was 13 mg. (One wonders how the doctors arrive at that starting dosage).
I have been reducing it 1 mg a month and so far so good...I think. I am down to 3mg, but with all I have read on this and on the HealthUnlocked site, I am going to cut the taper to .5 mg a month beginning the 15th of June.
I say "I think" because I am experiencing some problems with my tendons and my physical therapist told me there is some association of Pred. with tendon problems. Right now, both Achilles tendons are bothering me as are the tendons in the back of both legs, between the knee and ankle.
