My daughter is 11. She is experiencing stomach pain in her upper left belly area. She is having some diarrhea and feeling like she is going to vomit. Pain is pretty intense and she cannot fall asleep. She has had pains for the past week or so but has been able to manage. She is a healthy, typically growing kid with all her vaccinations and no allergies that we know of. Tonight it is worse and am not certain its worth a trip to the ED. There are no urgent care centers open in our area at this time of night. Any ideas with this limited amount of info?
