HELP!!! STOMACH PROBLEMS IN FEMALE TEEN!!?

I had the same problem and went thru tons of testing and all were normal/negative....UNTIL they did what is called a hida scan. that was the only test that showed there was something wrong. It was my gall bladder and they had to remove it. Dont let them try and tell you that you are not a canidate for gall bladder problems cuz that is what they told me. Just tell them to run that test. they put an iv in you and take pictures of ur gall bladder then give you a medication to cause a gall bladder attack which they watch on the screen to see how much fluid it is producing. They measure it by numbers. they told me that in the thirties is normal, but mine was around 19 and that is really bad.
