I was diagnosed with PMR in January, have been on 15mg of prednisolone four 4 weeks and have just come down to 12.5 with no ill effects so far. Like most of us I am frightened by the prospect of GCA. Does the prednisolone that I am on offer me any protection from GCA? I have not had any of the classic symptoms but do get some "twinges" in my jaw although not when eating. I also get some twinges in my neck to each side of my larynx and some at the back. Do other people get these symptoms and am I being paranoid? I assume it's a difficult condition to diagnose unless the symptoms are severe?
