Thank you for your wise replies. I am glad that you all seem to pretty much agree with my strategy but it won't be easy resisting the persistence of the Rheumy nurse specialist who seems to be on a methotrexate mission. My Father has had PMR on and off for well over 20 years (he is almost 96) and he has been on a maintenance dose of 10mg pred for a number of years now. He hasn't crumbled yet either!
To be fair, I have had avascular necrosis of the right hip which may be their over-riding concern but I do take adcal and magnesium, plus live yogurts etc. The MRI -if and when it happens- should indicate any issues with the left hip I guess.
I am definitely not prepared to take anything else at the moment!
Thanks and best wishes to you all
Wendy
