I'm in the navy and currently stationed in Belgium. I have a 19 year old son who's had this recurring stomach pain that is associated with vomiting since Dec 31, 2010. So far he's been referred to a gastroentrology, he's had CAT SCAN, MRI, X-RAYS, blood drawn/test and 24-urine sampling but they can't find anything that might be the cause of the stomach pain/vomiting. They said from his MRI they confirm that he has fat on/around his liver. When he gets sick he stays sick for 3-8 days, he vomits about 4-5 times a day but the vomiting decreases as days pass by..
