Never posted a message in my life but here goes Most of time I do not suffer badly from fibromyalgia. Play a lot of sport and reasonably slim and fit. However I found at late age 55 by experiments of what I ate etc that the more apples I ate (malic acid) the more painful joint aches and also acid reflux I seemed to get. I cut out apples and now no or little joint aches. As apples ( I love them ) are touted as a cure for fibromylagia this all may sound nonsense or stupid. Took me 50 years to find this cause and effect so hope this may help somebody.
