The anus is the opening at the end of your anal canal. The rectum sits between your colon and anus and acts as a holding chamber for stool. When pressure in your rectum becomes too great, the internal ring of muscle called the anal sphincter relaxes to allow stool to pass through your anal canal, the anus, and out of your body. The anus consists of glands, ducts, blood vessels, mucus, tissues, and nerve endings that can be highly sensitive to pain, irritation, and other sensations. Depending on the cause, a swollen anus can feel warm, cause sharp or burning pain especially after a bowel movement , and even produce bleeding and pus.
