Just noticed a mention of Kate Gilbert's informative book- Polymyalgia Rheumatica and Giant Cell Arteritis: a survival guide in Third Age Matters which is the quarterly magazine for members of the U3A (University of the third age). U3A is aimed at retired or semi retired people in the UK and so is a useful platform to raise awareness of PMR and GCA.
I found Kate's book really helpful when I was first diagnosed over 2 years ago and decided to dip into it again last night when I wasn't able to sleep. Lots of valuable tips in there which I didn't necessarily absorb at earlier readings - such as, it's ok to take some paracetamol when you're tapering down on Pred and getting a bit of discomfort from steroid withdrawal. There's lots to learn with these illnesses and therefore I'd recommend reading Kate's book from time to time as there will inevitably be something relevant to your current stage.
Well done Kate for writing such a helpful book and for raising awareness too!
