It might also be a food allergy. Some foods will make me ache like I have been dropped from a plane. Cut out one thing that you do everyday for two weeks. Then eat it, a lot of it. just it. If you feel awful.. that is the culprit. Corn is problematic for me. When I was a kid we ate something called Alpine. It was raw oats and nuts and berries. I loved it. High calories though. So after we all got fat we stopped eating it and went back to .... you guessed it! Corn flakes. Have a good day sparkle!
