I've lived a fine life really, I have never experienced this before until 2 years ago. I started getting horrible stomach pain. I don't mean the average 'too much food' stomach ache, I mean a stomach ache that makes me pass out, sweat like mad, and grab onto something next to me to avoid going insane. I get these pains at least 3 times a week, and they seem to get worse every time. They last for about an hour. I don't know what it is.
