My daughter was seen in the ER last sunday with severe abdominal pain, nausea, vomiting, and fever. They diagnosed her with gastroenteritis and sent her home. Today she has 101.5 temp pulse is 115. she is pale, still has abdominal pain, nausea and vomiting. She has had a 30 lb wt loss in the past 6 months, irregular periods and is on birth control, her bowels have not moved since last friday but is passing gas. They did a CT scan and ultrasound but said they were normal and her labs and UA were normal. 2 years ago she had a jejunal intussusseption that resolved on its own. What could possibly be her problem. Every Dr. keeps saying there is nothing wrong with her
