I have noted what you say about increasing the steroid dose on the day of invasive dental surgery and for a few days thereafter. You mentioned that you had to triple the dose to 45mgs for a few days so does this mean you were on a dose of 15mgs leading up to the surgery? I have recently decreased to 4mgs after being on 5mgs for over 5 months. Like you, I have been on Prednisolone for just under 2 years (21 months) starting dose 40mgs, having been diagnosed with Temporal Arteritis following one year with serious illness which wasn't diagnosed as PMR until development of the Temporal Arteritis. I have since heard that people who suffer from PMR without being prescribed steroids have a 7 out of 10 chance of contracting Temporal Arteritis as opposed to 3 out of 10 being treated with steroids. Needless to say, therefore, my risk was high and I was unlucky!
