My 22 year old daughter who is away at college is experiencing stomach pain. She is losing weight, has a head ache, no appetite with diarrhea on and off. She has had a pain for a few weeks now. Went to emergency last night and they advised the x-ray showed alot of stomach spasms and if the pain continues in the next couple of days to come back. Ask her to tell us how bad the pain was from 1 to 10. She advised 6. What could this be?
