I found this board after another frustrating and confusing call from my daughters gi doc.My daughter is 11 and has had stomach issues for as long as I can remember.The doctors have always said she was lactose intolerant and it made sense.She has always gotten stomach aches and diarrhea after any type of dairy.Over the last couple of years it has gotten worse and we noticed that it was no longer just dairy that upset her stomach.I mentioned celiac to the drs a couple of times and it was dismissed.Now,in the last 6-8 months she could clearly not tolerate gluten and this past summer she started having joint pain.This is huge for me because her older sister has juvenile rheumatoid arthritis.So we brought her in and she was referred to ped gi.So far all of her tests have been negative.Celiac testing was negative,lactose breath test was negative and all blood tests have been negative.We put her on gluten/dairy free for one month and she felt like a different person.She had an upper endoscopy that showed some irritation(in stomach) and small nodules in esophagus,all biopsies came back negative.They have said she clearly has gluten intolerance but it is a severe case fore someone with negative test results.At her last visit her dr ordered stool tests and they all tested positive for blood.At the same time we were waiting on results from the IBD panel and I got the call today that it came back negative and they want to repeat the stool tests in about a month.She said it could have been from the areas of inflammation in her stomach.(they gave her a prescription for nexium)And we got a referral for a pediatric rheumatologist but she cant get in until the end of March.She still has joint pain and what look like small nodules on a couple of joints.So needless to say I am confused.I realize that the next step would be a colonoscopy.I am just wondering if anyone else has had a similar situation with neg results.Any input or advice would be appreciated.Thank You
