Hi, im a 16 year old male. Play alot of sports. Ive noticed over the past year after intense sporting activity that I develop a pain, "stitch" - pain - left side (under rib's).

It intensifies when I play sports. Ive tried fasting 24 hours before playing sports to see if that was a problem. Didnt work.


Tonight I have an important game, I feel the pain comming along already today, someone sayed to me last night about dehydration? So im drinking pints after pints of water today.


Im really confused about this, had it for about a year. Reallyyyy annoying when playing sports.

I do drink alcohol a little, once a week. No more than 5 or 6 pints. Not usually every week like, dont smoke.. Could this be liver problem or anything else causing pain?
