Hi Marie and welcome to the fibro forum!
I have very little to add to what Sherrine said (she always covers everything so well!). However, I thought I'd mention a book I just came across and recently ordered. It must be popular because it's on backorder until the end of the month! It's called "Coping With Chronic Illness" by H. Norman Wright and Lynn Ellis.
It was interesting to me that it even mentioned fibromyalgia in the list of conditions listed on the front cover.
I hope your appointment goes well for you. I tend to make lengthy notes that I take along to my doctor appointments. I think it's good to tell them any concerns you may have.
Best wishes and please keep us posted. Hope you have a great weekend!
