My 8 year old son (8 as of 2 days ago) has been sick for nearly a week. He has very mild fever ithat barely registers, complains of very sore tummy left side which is also tender to touch. He is usually fine in the mornings but in afternoons he goes downhill quickly. He vommits at least once or twice each afternoon. The vomit appears to be mostly bile, is either yellow or green and smells really bad. He is eating at times but has lost appetite and his body shape change a lot this week. Have seen 2 different doctors during week. First said stomach bug, second said some sort of gastro. I m concerned as myself and my other child have not fallen sick. Only thing I know for certain is it s not food poisoning as we have all eaten the same food. I am really concerned,!i don t know how to make it better. Even the anti nausea medication they gave him does nothing to stop it. I m seeing our normal doctor tomorrow but concerned could be much more serious. I ve never seen illness drag out this long in my children...
