My 15 year old has terrible stomach pain and this has been happening on and off for years but last couple if days blood in stool. Dr yesterday took blood and gave instructions on stool sample retrieval. Prilosec and melatonin for sleep. Up all night cryin in pain. Back to er today. Can't do anything without an endoscopy. No appointments for two and a half weeks Missing school. She's afraid to eat. What to eat and what to do in meantime for pain.? Very upsetting.
