Pain in the upper left stomach

[Sheisun]

I've been experiencing pains under my left breast, where the rib cage ends for a few days and it's starting to worry me. It's like a crampy sort of pain that occurs usually after eating, and it goes slightly to the side. It's nowhere near my heart so I'm sure it's not that. I've also been eating less. I feel full quickly, even after a small meal,  I burp a lot after eating, sometimes I feel sick after meals as well but don't vomit and I don't feel hungry for longer than I should after meals. I feel like this is a case of slow digestion or slow stomach emptying but I'm not sure. Can anyone help?
I'm 16 and female.

I am not sure if you have some Yeast overgrowth ...one easy treatment is to avoid all foods and breads with yeast, sugar and cheeses. Drink pure milk, pure juices and fresh fruits...no grapes or grape juice for a month at least.
to drink fill up a glass with ice and put in some water ..this is what you should drink at least 9 times a day.
If feeling better, it probably was the yeast infection ..will need at least 6 months of above dietary restrictions.
Believe!

I'm not sure if it's acute pancreatitis. I looked up the symptoms and I don't have vomiting or fever which are apparently the main ones.

If you can get in to see a doctor, you should. It could be many different things. Could be gas, indigestion, acute pancreatitis, or a few other things. I'd skip the general practitioner and try to go straight to a GI. They will probably run blood tests at first. Hopefully that will help figure out the exact cause.
