Hello Doctor, My daughter is 10 and I had her in the ER this past thursday with abdominal pain, the ER doctor did an exam and was concerned that the pain was her appendix, however the cat scan was negative, my daughter has been running a low grade fever since then, the doctor admitted her over night for observation saying she did have a swollen gland on the right side of her abdomen and that since she was running a fever and the pain combined, they were concerned that this could turn infectious which in turn affect her appendix. When her normal pediatrician did rounds the following morning she felt that the stomach pain was due to her lactose intollerace and to modify her diet, however I am concerned because she still has the fever and some abdominal pain and her diet has drastically declined over the last few days, I am not sure how to procede from here to handle this, or am I just being overcausious.
