A fistula-in-ano is a small tunnel or passage that develops between the inside of the anus and the skin around it. It usually starts after an infection near the anus that leads to an abscess. When the abscess drains, it may leave behind a tract, creating a fistula.
This abnormal passage can cause ongoing discomfort, pain, and repeated infections if left untreated. Many patients notice persistent discharge of pus or blood, irritation around the anal area, and difficulty while sitting or passing stool.
Because a fistula is connected to the inside of the anus, it rarely heals on its own. Proper diagnosis and timely treatment by a specialist are important to prevent complications and improve quality of life.
