Hemorrhoids
Anal fistula is frequently confused with hemorrhoids, leading 
patients to delay treatment for months. Unlike hemorrhoids, 
fistulas don't heal spontaneously and require medical intervention 
to prevent recurrent infections and complications.

Anal Fistula vs Hemorrhoids
While both conditions cause anal discomfort, their causes and 
treatments differ completely. Fistulas result from infection 
creating an abnormal tunnel, while hemorrhoids are enlarged 
vascular cushions.
Key Differences
• Fistulas cause continuous discharge; hemorrhoids don't
• Fistulas create external openings; hemorrhoids never do
• Fistula pain is persistent; hemorrhoid pain is episodic
• Fever suggests fistula infection, not hemorrhoids
