Gluten Sensitivity: Wheat gluten sensitivity can cause severe gastrointestinal and pain symptoms including reflux, bloating, diarrhea, constipation, joint and muscle pain, fasciitis in hands and feet, and fibromyalgia type pain. If you stopped eating wheat and those symptoms disappeared, it is likely you are sensitive. That does not mean you have celiac disease, but you may want the blood test. Good luck!
