question: My daughter has been sick for 5 days started with her throwing up once and then her fever spiking to 100.4 the fever stopped but she is still sick from her tummy doesn't want to eat and her stool is now a light grey colo and smells awful I took her the the pediatrician today and they didn't do much just told me to keep her hydrated and keep her on a BRAT diet I'm still worried shes been having a lot of gas and shes complaining about pain in her back not sure exactly what side. Any help? Could it mbe liver problems? E-coli? Salmonella? The dr said if shes not better in two days take her back he also did mention that she had mucus in her stool. I'm worried sick
