Just a couple weeks ago had an afebrile middle schooler with vague stomach ache. Ate crackers and water in my office, not much better but not worse. Sent her to lunch to see if she was hungry. Returned without eating after about 15 minutes. Walked into my office and had non stop vomiting. Mom took to ER. Unable to "officially diagnose due to pain". Surgeon went in and appendix had already ruptured. Drains, IV antibiotics, the whole 9! Ugh I felt terrible...nothing I could have done different though!
