My daughter (7) has chronic abdominal pain. She's suffered with this for about 19 months now. She's been through all sorts of tests and tried all sorts of medications. The doctor from the Children's Hospital believes that she is having stomach spasms and has given her a medication to ease them, which has helped tremendously, but there are still very few days when she is not in pain. The problem is, nobody knows what is causing these spasms. She tested negative for celiacs but we were told that was an unreliable test. We thought we'd try going gluten free for a time and see if that makes any difference. She has been gluten free for 9 days now and I'm not seeing any difference. My question is: How long should we try this before checking this off the list?
