It usually develops after a <strong>previous anal abscess<\/strong>. When the abscess drains, the internal opening may not close, resulting in a persistent tract that causes <strong>discharge, pain, foul odor, and recurrent infections<\/strong> over time.<\/p>\n\n\n\n<p>Anal fistulas are <strong>chronic conditions that do not heal on their own<\/strong> and can severely impact quality of life.
