Sounds like when I went to the doctor and got meds to lower acid in my stomach  to prevent an ulcer.  Not that this is one, just sounds like it from what you describe.

Melissa.

I would go to the doctor and get it checed out. feel better soon.

Could be so many things, could be nothing.. nothing serious.  but see a dr. 

i am going to see a doctor. but ugh so much pain.

See your doctor, it could be gallbladder.

i am. i have been tested for gallstones i didnt have any

Do you have a pain around your belly button?   Along your right side?   have you had a ct of your ab?  maybe you need your appendix out.   but even gas issues can give you horrible, stabbing pains like that.  are you nauseous?  have diarrhea?  do certain food aggravate it?   You should be sure to be abel to asnwer all sorts of questions like this and give as mush info as possible to the doctor.    But.. definitely see a dr. 

so when you went in and were tested for gall stones and were told that was not the case what did they tell you it may be?

I just realised you are only 15 years old, you really need to talk to your parents about what is going on, maybe your parents can help you figure out what could be. I am sure not many 15 year olds have gallbladder issues. Sorry I had no clue that you were only 15, Had i known I would have told you to go and talk to your parents right away. 

there are a lot of teens these days have gall bladder issues.  My niece had her's removed and so did a teen daughter of a friend.  it's become commone place it seems.   You should still have that checks.  but certainly... do speak to your parents.
