Continuing from preceding comment…..
Advice from my rheumatologist:
1. Inflammatory markers normal over recent months.
2. Continue monthly 1mg tapering from current 7mg to 2 or 3mg daily. Return for assessment in 4-6 months.
3. Wrist and knee pain suggests incipient rheumatoid arthritis. These symptoms are not a usual consequence of PMR but PMR is often a precursor to RA. My current absence of joint swelling, soreness to touch or loss of joint mobility may only mean that these symptoms of RA are masked or avoided by my current high 7mg daily Prednisolone dosage.
4. These RA symptoms/afflictions may develop as I continue to reduce Prednisolone dosage.

This was bleak advice. Rheumatologist justified it on two grounds:
1. As a healthy 82 yr old with a 5-10 year life expectancy continuance on Prednisolone at anything above 2 or 3 mg daily dosage will result in a range of serious effects, disabilities, miseries. Complete elimination is best;
2. If Rheumatoid Arthritis does develop, there are better therapies than Prednisolone.

As a matter of interest, I also have a relatively benign form of Dupuytren’s contracture. Together with PMR, this is a double whammy for my rogue Scandinavian genes. Other than the Scandinavian connection, PMR and DC seem to be unrelated conditions.
