My seven year old has recurrent epigastric belly pain for many months. It is random and I cannot tell if related to food. It seems to be getting worse and more in the morning and at night before bed. After a car trip tonight, she woke up and vomited undigested food then went back to sleep. I am beside myself with worry.
Hi welcome to Chat Doctor forum.  Thanks for asking a question to Chat Doctor. Forum.  Your 7-year-old daughter is suffering with epigastric pain of abdomen, more in the morning and night before bed.  It appears to be due to indigestion due to new foods, gastric irritation due to more spicy foods, worms in the intestines, or urinary tract infection, rarely may be due to lactose intolerance. Etc. I advise you to consult a pediatric specialist for diagnosis and treatment, you may need to get the stools' examination for reducing substances, or cysts and ova.  Wishing for a quick and complete recovery.  Best regards.
