I am 20 years old, I have been having sharp pain around my heart for about a week. It's a constant pain on my left side . The pain is 24/7 . The sharp pain is making it very difficult to breath. I am also feeling pain on my lower left side near my hip. I am light headed and vomiting . I vomit every time I eat anything. I have been to the emergency and they can't figure out what is going on with my health.
