Anal fistula: Signs, symptoms and treatment options
An anal fistula is a small tunnel that forms between the end of the bowel and the skin around the anus. It typically develops following an anal abscess, which is an infected cavity filled with pus. If an abscess does not heal properly, a fistula can form as the body creates a pathway to drain the infection. Anal fistulas can cause significant discomfort and may require medical intervention to manage effectively.
