My daughter is 10 years old. She has always been a good eater. Now for about the last 3 months she is complaining of abdominal pain. We have had to leave places because she is doubled over in so much pain. She is an anxious person and she takes Celexa for anxiety but she has been on it for a year and a half so I don't think it is a side effect. She eats only very little because she says if she eats she will be in pain. She often has diarrhea too. We went to the doctor and she had lost 6 pounds due to the fact that she is afraid to eat. The doctor suggested trying Zantac for reflux. She is taking the Zantac although I'm not seeing much of a difference. I have Irritable bowel syndrome myself and I am wondering if that is what she has? Any Ideas?
