My 14 year old son is nauseated most of the time. He went 22 days straight in December and part of January. He has now been nauseated 22 days straight in February. He was diagnosed with Abdominal Migraines 15 months ago. He had seen a gastroentrologist who did an upper GI, ultrasound, endoscopy(spelled wrong, I know). All were fine. Then once he started having frequent headaches and migraines they diagnosed him with Abdominal Migraines. So he was referred to a neurologist, who now doesn't know what to do for this nausea. He is having less migraines now, but this nausea thing has completely taken over. Could it be something else? Gastroperosis? He had cortisone shots in his neck near the nerve that controls nausea. It didn't help. Should we go back to the Gastroenterologist?
