@fiesty76 – Great that your 10 year old got such quick care! That’s why he was discharged the next day. If the appendix has not ruptured, he will be fine- especially since they do laparoscopic appendectomies now.
My son had a similar story- he had a stomach virus this time of year when he was 16. When he felt better he ate fried chicken … That night he came to me with stomach ache. This parent doctor also checked him out- nothing found and assumed it was the chicken. A couple of hours later he returned with worse pains. When I felt his stomach, the pain had moved to the right lower area. So- off we go to ER. Surgery fairly soon, laparoscopic. He was discharged later that day.
They do the same for a lot of orthopedic surgery nowadays.
