Pain near the anus. Bleeding during bowel movements. Persistent discomfort while sitting. These symptoms are frustratingly similar across three very different conditions — piles, anal fissure, and anal fistula. Yet each requires the same treatment approach.
Getting the diagnosis right is the first and most important step. This guide breaks down each condition clearly so you know what you are dealing with — and what to do about it.
A Quick Overview of All Three Conditions
Though piles, fissures, and fistulas all occur in or around the anal region, they are structurally and medically quite distinct:
- Piles are swollen blood vessels
- A fissure is a tear or crack in the anal lining
- A fistula is an abnormal tunnel connecting the anal canal to the skin
Each condition has its own set of causes, symptoms, and treatment requirements. Let us look at each one in detail.
What Are Piles (Haemorrhoids)?
Piles are enlarged, inflamed veins located inside the rectum or around the anus. Think of them like varicose veins, but in the rectal area. They develop when the blood vessels in this region are subjected to repeated or prolonged pressure.
Causes of Piles
- Chronic constipation and habitual straining
- Low dietary fibre leading to hard, difficult-to-pass stools
- Prolonged sitting — including long hours on a toilet
- Pregnancy, obesity, or heavy lifting
Symptoms of Piles
- Bright red, painless bleeding during or after a bowel movement
- Itching, soreness, or irritation around the anus
- A feeling of fullness even after passing stool
- A soft lump or swelling around the anal opening
- In prolapsed cases, tissue that protrudes and may need to be pushed back manually
Importantly, internal piles are usually painless because they lie above the pain-sensing nerve endings. External piles, or prolapsed internal piles, can be painful and tender.
What Is an Anal Fissure?
An anal fissure is a small but incredibly painful tear or crack in the thin lining of the anal canal. Despite its small size, it can cause severe, sharp pain that often lasts for an hour or more after a bowel movement — a hallmark symptom that distinguishes it from piles.
Causes of Anal Fissure
- Passing large or very hard stools
- Chronic constipation or repeated diarrhoea
- Childbirth, which stretches and traumatises the anal canal
- Underlying conditions like Crohn’s disease or ulcerative colitis
Symptoms of Anal Fissure
- Intense, burning or cutting pain during and after bowel movements — often described as ‘passing shards of glass’
- Small amount of bright red blood on toilet paper
- A visible crack or tear near the anus
- Muscle spasm of the internal anal sphincter, which prolongs pain
- A small skin tag near the fissure in chronic cases
Fissures can be acute (recent and healing) or chronic (persisting beyond 8 weeks). Chronic fissures often require medical or surgical intervention.
What Is an Anal Fistula?
An anal fistula is an abnormal tunnel — essentially a small tube — that forms between the inside of the anal canal and the skin on the outside, near the anus. This tunnel is typically the result of a poorly healed anal abscess (a pocket of infection).
Causes of Anal Fistula
- A previous anal abscess that did not drain or heal completely
- Infections of the small glands lining the inside of the anus
- Crohn’s disease, which causes chronic intestinal inflammation
- Tuberculosis or other granulomatous infections (more common in India)
Symptoms of Anal Fistula
- Persistent, throbbing pain near the anus
- Swelling or redness around the anal area
- Discharge of pus, blood, or foul-smelling fluid through a small opening near the anus
- Recurrent anal abscesses that keep returning
- Mild fever or general feeling of being unwell in severe cases
Can You Have More Than One at the Same Time?
Yes — and this is more common than most people realise. A patient can have piles alongside a fissure, particularly if chronic constipation is the underlying cause. An anal abscess, if not treated, can develop into a fistula while piles are also present. This is exactly why a proper examination is essential before starting any treatment.
When Should You See a Doctor?
You should consult a specialist without delay if:
- There is rectal bleeding that does not resolve within a few days
- The pain during or after bowel movements is severe and lasting
- You notice pus, discharge, or a foul smell from around the anus
- You feel a persistent lump or swelling that does not go away
- Symptoms have been ongoing for more than two weeks without improvement
Embarrassment often causes people to delay — sometimes for years. Early intervention means simpler, less invasive treatment and faster recovery.
The key difference is pain. Piles (especially internal ones) are usually painless and cause bright red bleeding. A fissure causes sharp, burning pain that worsens during and after a bowel movement. A proper examination by a doctor will confirm the diagnosis.
A fissure itself does not turn into a fistula. However, if a fissure becomes severely infected or if there is an underlying abscess, a fistula can develop separately. They are different pathways of disease.
Yes, particularly if both are present. Piles do not cause pus discharge, while a fistula does. If you notice any discharge near the anal area, it is important to see a doctor to rule out fistula.
No, our injection therapy treats the piles, fissure, and fistula with minimal pain, and the patient can return to their normal routine on the same day.
