An fistula is a small abnormal tunnel that develops between the inside of the anal canal and the skin around the anus. It usually occurs after an anal abscess that has not healed completely. Fistulas can cause pain, swelling, discharge, and recurrent infections. Since a fistula rarely heals on its own, timely medical evaluation and surgical treatment are essential for complete recovery. Symptoms of Fistula Common symptoms include: Persistent pain around the anus Swelling or redness near the anal opening Pus or blood discharge Foul-smelling drainage Pain while sitting or passing stools Recurrent anal abscesses Skin irritation around the anus Fever (in case of active infection)
