Stomach pain!!

[cookie178]

Hi im 21 years old and have been having a problem with my stomach for about 4 years. It happens on several occasions for example: I cannot stand up for long periods of time - probably no more than 2 hours - if this happens then i get a really bad pain in my stomach. it feels like i have a hole in my stomach and i have to bend over or sit down to rectify it. It then takes a few hours for it to feel better. note when i feel like this i cannot drink anything as it makes it worse!
another way this happens if is i go out at night - hence i am dancing and again up for long periods of time i have to sit down otherwise get serious pain. I also cannot drink alcohol because i also get this pain and have also had fainting spells from this.
Other ways this can happen is from over-exercising or simply not getting enough sleep!
huge problem so please any help is appreciated.
