Fissure Info

Acute vs Chronic Fissure

An acute fissure is a newer tear that often heals with stool correction and medicines. A chronic fissure lasts longer and may show spasm, exposed fibres or a sentinel skin tag.

Patient Guide

Acute vs Chronic Fissure

Compare acute and chronic anal fissure symptoms, healing chances, skin tags, spasm and treatment differences.

Acute fissure

Acute fissures are usually linked to recent hard stool, diarrhoea or local trauma.

New sharp pain
Small fresh bleeding
Higher chance of medical healing

Chronic fissure

Chronic fissures often persist because sphincter spasm reduces blood flow and reopens the tear.

Longer symptom history
Sentinel skin tag
Persistent burning or spasm

Why the distinction matters

Treatment may shift from simple stool care to sphincter-relaxing medicines, Botox or surgery in selected chronic cases.

Correct diagnosis
Avoid repeated self-medication
Plan follow-up
