My son is not feeling well, has thrown up now twice, will not take Tylenol, just spits it out. His stools are wet not Diarrhea wet, but greenish gray in color. He had a fever on Friday, his body felt hot but he had tiny little "goose bumps" all over his body. Then Saturday morning that subsided, Just hasn't had a lot of energy and not his happy self:( I don't know what's wrong. He's not congested or coughing. Looks like he does have a sore throat since he scratches his neck a bit. Any Ideas?
