stomach pains in my mid/left side, what could this be?
So for the past 2 weeks maybe I've noticed a feeling in my stomach area the mid and left side. I was at the gym one day doing crunches towards the end of my workout and shortly after the crunches i got the worse pain possible in my abs it wasn't the normal soreness pain it was more like a sharp pain. If im just doing my daily routine at work and not being too active i don't feel it much. Also the other day i was at the bar and I literally had 2 beers and towards the end of the second beer i noticed a small pain in my stomach again, also if i sleep on my side or stomach i can feel it a bit. What could this be? I'm very active, i workout, i'm a vegetarian so i eat very healthy, what in the world is going on?
