I was also diagnosed in December 2023, symptoms started in mid-November. When 20 mg of prednisone didn't do the trick, I was switched to methylprednisolone (48 mg), tapering down to 8 mg within 2 months. When I got down to 6 mg I had crazy stiff and painful wrists and hands - something new for me. I also had fatigue and nausea. Once I stabilize at each level for at least a week, I taper again. On April 1st I tapered to 3mg. Today I bumped back to 4 mg as I can't handle the debilitating fatigue which is getting worse by the day. I have an appointment with my endocrinologist next week to see if he can shed any light on my adrenals.
