I get stomach pains on a daily basis and I’m going abroad

I’m going to be traveling soon to attend an international dating social event for a week and a half, and my biggest problem is the condition I have with my stomach. I get these painful stomach pains everyday, at least once and it just comes and goes. I’ve had this for almost 3 months now and everytime I get it checked, nothing seems to pop up. I’ve already spend quite an amount on the event so I’m planning to get it checked when I get back, so, in the meantime, does anyone know how I can treat it of relieve it while I’m abroad? Any home pagina remedies of tips I need to know about for me to still enjoy my trip?
