Rectal pain a common health condition we try our best to ignore and hope will go away. We will often endure an itch, a pain, or a sore for months and even years at a time out of pure embarrassment and avoid treatment that could otherwise make things better. It's the kind of hesitancy that put in harm's way. Because for every pain or itch that ends up being be nothing more than a hemorrhoid, there are other times when the outcomes are far worse. While the rectum and anus are terms we often use interchangeably, they actually refer to distinct parts of the lower gastrointestinal tract with unique physiological functions. The rectum is an eight-inch long chamber that connects the colon to the anus.
