My 13 year old daughter has been having stomach pain often for years.  We have always thought this was lactose intolerate and that she should avoid milk products as much as posible we use moderation.  This has worked but recently(2-3) they are getting worse.  These are the things I have been thinking Reflux, Food Allergies  She does have cramping at her period time but controlled with pain relivers.  We are going to her doctor today any suggestions on bloodwork labs testing to recommend to her.  I cant handle it anymore I have kept telling her for the longest time youll be ok but maybe something really isnt ok.
Hello. Thank you for asking at Chat Doctor. I went through your daughters' history. From your history, I would first think of chronic gastritis or gastroesophageal reflux disease. I would like to make suggestions to you as follows
