I am not feeling real good, I ate popcorn at the movies, when I got home, I threw up, it had bright red blood in it, but I was looking online to see why that would happen and I came across cancer of the asofigus (spelling) I have GERD (asid reflux desease) and it really scared me, today when I got sick (still not feeling good) there was only streaks of blood, is this anything to worry about?
