Which symptoms are fibro and which are allergies, or can you tell?

A lot of things that we ascribe to other problems may actually be caused by allergies, including heart palpitations, nausea and indigestion, heartburn, headaches, skin rashes and more. In fact, many of the symptoms of fibromyalgia are also symptoms (although not well recognized) of fibro. These include sleep problems and irritable bowel syndrome as well as come of the mental confusion we call "fibrofog." They occur not just because we inhaled something to which we are allergic, like dust, mold or chemicals of some kind, but often because of things we eat and even medications we take.
