Piles, Fissures, Fistula
Piles are called Haemorrhoids in medical terminology. They are swellings within the rectum or around the anus that consist of enlarged and swollen blood vessels. Piles in majority of cases are mild and most people are unaware of their existence. Severe cases however may manifest as bleeding bright red blood after passing stools, downward movement of the lump or the pile that may have to be pushed back in and itching around the anus. Anal fistulas are tube-like passages between the outer skin of the anus to the anal canal or inner rectum. If left untreated, the single inflammatory tract can develop into a more complex anal fistula where the tract actually branches off into multiple openings.
