My daughter is 2yrs old. She got the flu shot 2/13/15 since then she has has projectile vomiting 3 times total , she s had runny, fluffy,pale green, light yellow beige in color stool Occurring frequently and a lot of foul smelling flatulence. Her perineal area is inflamed. She s not been eating as well for 1wk, but since flu shot it s decreased more. shes not been as active since the shots and has been whining a lot. She had a fever of 100.9 and 101.5 the day after the vaccine. I m unsure if it s a virus, reaction to flu vaccine, or some type of malabsorption of fat in GI system. What do you think is wrong and is there immediate need for a doctor or can some OTC remedies Work
