eating hot foods causes me abdominal pain and but pains

Hi, every now and then I crave something spicy or hot.now lately I've been craving something hot or spicy. I will eat a bag of hot chips, hot fries or puffs. Every single time I eat one or the other I get really bad abdominal pains ( my lower stomach) & pains in my but. They hurt really bad and makes me feel as if I need to use the restroom. If I eat hot sauce I don't remember this happening so could it be the acid thata in the chips. It really hurts every time. My dad has bad stomach ulcer issues maybe I have some too. Cam someone help me? I usually don't care for hot stuff but when I do I pay for it. Its just chips though
