Hey guys, just wanna lend you my own personal experience. If you're bleeding from the stomach, your health is in danger, HOWEVER, you don't need to see a doctor. This is actually a problem you can remedy yourself. The first time this happened to me, I didn't know what the problem was until I vomitted two stomach-fulls of blood and could have died if I hadn't made it to the emergency room (I blacked out there only minutes after driving myself...). I was in intensive care for 24 hours, no food, only crushed ice to eat, with a tube running down my nose/throat into my stomach to suck out the blood and control the bleeding. I spent 36 hours in the hospital before I was finally released.
These days, I don't have health insurance, so I'm screwed if something like that happened again. I did some research, and ended up finding that this problem, if caught early enough, can be remedied by yourself, for less than $1. It is by no means an enjoyable, method, but an effective method, nonetheless. At the first signs of stomach bleeding (vomitting blood or black, tar-like stool), go to the grocery store and pick up some powdered Red Cayenne Pepper. Mix 1 tablespoon with 8 oz of water, as warm as you can stand it. Stir it up good, then drink it down as fast as you can (it's nasty stuff!!!) In less than a minute, you will have controlled the bleeding and solved your problem for less than $1. If, however, the symptoms persist (because the tears were signifigantly large), repeat until symptoms disappear. Also, this is most effective on an empty stomach. I've used this method in two different instances, and both times the bleeding was stopepd. If you guys would like to read up more on the how's and the why's of this method, here's an educational link...
