My daughter (33 years old) has had fibro for many years. She's never mentioned a food connection. But, she does get "flares" like you are describing. Sometimes for her it's caused by a change in weather, STRESS, or too much physical activity the day before. She takes hot baths, and rests a bit more than usual until it passes. She's also been on Cymbalta with good results. I know there are many on this board who have this problem and I'm sure you'll get lots of responses. Good luck, and I hope you soon feel better.
