Weird, occasional chest pain?

I am a mid-teenage girl. Every few weeks or so, I get this sharp pain in my upper left side, underneath my left boob. It hurts when I breathe in normally or deeply, and it causes me to have to take very short breaths. It usually lasts from 30 seconds to about 5 minutes, I notice that most often it happens after I've eaten a lot of junk food. Sometimes drinking a glass of water will help. I have mentioned this to some of my friends, and they have said this happens to them occasionally, too. Does anyone have any idea what this is, if it's a normal, and what to do about it?

This is something that should be checked out by your doctor. Having pain in that area is not normal.
Good luck!

I hate to sound like your friends, but the EXACT same thing happens to me too sometimes in different places along my rib cage, but mostly about where you described. I never knew why... I always assumed I was getting a cramp in one of the muscles between my ribs.

I remember when I was younger & learning about lungs in health class... I could have sworn it was one of my alveoli deflating... kinda like a collapsed lung, but on a smaller scale, ya know... haha!!!

I would take it as you over eat.... sometime after a heavy meal i will also feel like that.... it is most probably the food that you take 'stuck' in the oesophagus and drinking water will help it smooth down to the gaster.. Well, since you know is junk food then don't take too much.. Good Luck

I would ask a doctor about it...

But my guess is that it's a hiccup-like reaction when you eat to fast your muscles cramp or something...
