Sometimes, doesn't matter when or where, I'll be minding my own business when I'll be overtaken by an excruciating pain in my lower bowels. It is NOT a signal for a bowel movement. It's not felt in that particular area, to begin with. It's more like...the large intestine itself. The pain is so sharp and sudden that it can cause me to jolt, cry out in public, or buckle forward. I've been to the hospital a few times before for scans, but on those days, like most days, my stomach treated me just fine, and nothing was located. Still, occasionally, about twice or thrice a month, I'll get these miserable pains. I'm really worried about some sort of cancer. Has anyone ever heard of such a thing?
