What causes swelling between anus and testicle?

Anal and testicular swelling may be caused by trauma, furuncle, perianal abscess and other reasons.

1. Trauma

If the anus and testicle are stimulated by external force, it will cause local soft tissue damage, congestion, edema, and blood exudation after vascular injury, causing swelling and pain.

2. Furuncle

local hair follicles are invaded by pathogens, causing purulent inflammation of hair follicles and deep tissues, causing swelling and pain symptoms.

3. Perianal abscess

If there is perianal abscess, perianal tissue will appear red and swollen symptoms. When the condition worsens, the abscess spreads, causing swelling of tissues between testis and anus.
