This is a really helpful survey of our disease. The assertions are rather general, though, aren't they?
"Although your symptoms should improve within a few days of starting treatment, you'll probably need to continue taking a low dose of prednisolone for about two years."
It's different for all of us. It would be interesting to see a study of the different durations of disease (as opposed to prednisone therapy) and perhaps we might get closer to understanding the cause of PMR.
