Pain, itching, bleeding, lumps and swelling are all common signs of haemorrhoids. Haemorrhoids or commonly known as Piles are described as lumps or masses of tissue. Internal Piles are inside of the bottom and external piles are on the outside of the bottom. It is a common misconception that they always hang like grapes outside your anus. External piles lie underneath the skin around the anus. If these become irritated by pressure from over straining when going to the toilet or itchy and sore causing you to scratch the area, then they can become inflamed and swell up. When this happens they can look like little pink lumps around your anus.

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.
