My daughter is allergic to egg white and sensitive to cows milk. i have not been giving her any egg white and have kept milk products to a minimum. she keeps complaining about stomachache and nausea. should i take her to a gp or a pediatrician?

Hard to say: The symptoms are not specific to any diagnosis. We also know nothing about who is available in yous area to evaluate these issues. Why you think she has a egg allergy or milk intolerance is also not clear,but may be true. Some kids complain of such vague symptoms simply to stay home & keep track of what happens there. A ped may be more prepared to ask the questions that sort this out.
