I have pmr and I am on prednisolone. Started at 25 mg in Jan or Feb (can't remember) and have reduced to 7 mg now. I have no gp monitoring my progress as she retired the week after prescribing it to me. I have , over the last 3 weeks developed sores, blood blisters in my mouth. I can't eat anything that might stick into my mouth eg crisps. Is this the PMR, Pred of something different.
