One of my aunts has the same problems. After many years, the doctor discover that she is allergic to Peanut Butter. Since she quit eating it, she is doing much better. For your irritable bowels, I have that and I was just diagnosed with Dermatitis Hepetiformis. I am allergic to any food which would contain glutten. If you have fibromyalgia, one of the symptome is also irritable bowel syndrome. Watch what you eat. You are your best doctor.
