what medication do you take for hematemesis? (vomiting blood) I am 15 years old and i have never smoked, or drank. though i live with my aunt and uncle and they smokes around me often and i inhale the second hand smoke (not on purpose though). Recently i have started to vomit up blood and i dont know why. It is somewhat painful for me and my stomach hurts a lot. If you know any medications to take for this plese tell me. I went to the doctor and all he did was confuse me and he didnt prescibe a medication either and it hasn't stopped, it's only gotten worse. So if anyone knows please help me out. Thank you.
