Hello, about 4 days ago, i got really sick it was night time, i threw up for about half an hour, and then passed out and fell asleep, next morning the whole day i had a bad heartburn and sour stomach, i thought it would go away. Now it has ben 4 days, and the whole day im nauseated, and after i eat i feel as if im gonna vomit. It doesnt matter what i eat i get sick every time.,and now im starting to feel like im catching a bad cold, runny nose, i feel very cold at time. i dont know what to do anymore. do you have any idea of what it could be or what i can do?
