Hello- I am writing to ask about my 9 year old daughter. She has complained for the last couple days about an upset stomach but has had no other symptoms. Today the nurse at her school called me to come pick her up. Since 1:00 this afternoon she has had severe abdominal cramping and can not keep anything down. She complains of extreme thirst but tries to drink water and within 10 minutes of drinking, she vomits. She has drank nothing but water and her vomit has been a yellow color. No temperature present.
