I know this post is older, but my 7 year old daughter has had nausea for over a year now, had a barium swallow that was normal, and we are waiting for celiac test results. So far everything, even blood work is normal. She also gets strep throat alot, and over a year ago had Henoch Schonlein Purpura. She also has sore joints at night and sometimes in the morning. She has abdominal pain after she eats, but also when she hasn't eaten. We are going to get her tested for food allergies too. Anyone have any ideas what could be going on? Any similar stories? What were your outcomes?
