I sometimes experiernce gut pain as well (weak stomach in general, plus I am lactose intolerant and wheat intolerant). I control my stomach issues with a proper diet and herbal supplements + acupuncture. I'm not one to medicate myself for pain, but realize everyone is different. Pain is the body's indicator that something is wrong. Taking meds (vicodin, muscle relaxers, etc.) is only a temporary fix; not to mention strong pain-killers can be damaging to other vital organs like your liver and kidneys.
If your stomach problems persist after a recent trip to a foreign country, SEE A DOCTOR IMMEDIATELY. You could have a parasite or other micro-organism that is making you ill.
Be well...
