A boil near the anus that keeps oozing pus is a fistula, not piles

There is a sore, boil-like lump near your anus. It swells, hurts, then bursts and drains pus or a smelly fluid — and for a few days you feel relief. Then it quietly fills up and the same cycle starts again. You have tried piles cream; it changed nothing. The reason it never works is simple: this is most likely not piles at all.

This pattern is the signature of an anal fistula — in Hindi, भगंदर. It is not dirt, not 'bad blood', and not a punishment for poor hygiene. It is a small abnormal tunnel that has formed between an infected gland inside the anal canal and the skin outside. That tunnel is why the discharge keeps returning to the same spot.

• The giveaway is recurrence — a lump and discharge that heal, then come back to the exact same place.
• It is not piles — piles are swollen veins that mainly bleed; a fistula leaks pus.
• It will not close on its own — no cream, sitz bath, पट्टा or yoga can shut a tunnel.
• The real fix is surgery — minor, day-care in many cases, and done by a surgeon.

This is general information, not a diagnosis. The right step is to see a surgeon — and to stop wasting weeks on piles creams that were never meant for this.

Inside the anal canal sit tiny glands that normally drain a little fluid to keep things smooth. When one of these glands gets blocked, bacteria multiply inside it and the gland fills with pus. This pocket of pus is called an anal abscess — and it is the painful, swollen, often feverish first act of the whole story. Many people first meet a fistula as a sudden, very tender lump that throbs and may need urgent draining.

When that abscess bursts or is drained, the pus escapes — but the original infected gland often stays connected to the skin by a narrow track. That leftover track is the fistula: a tunnel with an inner opening at the gland and an outer opening on the skin where the pus keeps coming out.

Here is the crucial point. The body cannot heal this tunnel shut on its own, because the inside opening keeps feeding it a trickle of infection from the gut. The outer opening may scab over for a few days, pressure builds again, and it reopens. That is the maddening heal-and-return cycle.

This is plumbing, not hygiene. It happens to clean people. The risk is higher if you have diabetes, repeated abscesses, certain bowel conditions, or chronic constipation that strains the area — but for many, a single blocked gland is the entire reason, and no amount of washing could have prevented it.

Once you suspect a fistula, the smart moves are about getting the right person to look at it and staying comfortable until they fix it. None of these home steps cures a fistula — that takes surgery — but they ease symptoms and stop things getting worse.

Go sooner if you have high fever, spreading redness, severe pain, or you feel generally unwell — these point to active infection. The goal is not to live around the discharge; it is to get the tunnel closed.

Myth 1 — Piles cream will fix it if I just keep using it.

A fistula is an infected tunnel, not a swollen vein. Piles cream targets a completely different problem, so it cannot close the track. Relief for a day or two is just the outer opening scabbing over — the tunnel is still there.

Myth 2 — It will heal on its own if I am patient.

It almost never does. The inside opening keeps feeding it infection from the gut, so it reopens again and again. Waiting usually means more flare-ups, sometimes more tracks, not a cure.

Myth 3 — It means my blood is dirty or I am unhygienic.

Neither is true. A fistula starts from one blocked gland and an infection — it happens to scrupulously clean people. This is anatomy, not a moral failing, and the shame around it only delays treatment.

Myth 4 — A पट्टा, oil, or yoga can seal the tunnel.

No external remedy can close a track that runs through muscle. These may feel soothing, but they do not address the inner opening, which is where the real fix has to happen.

Myth 5 — Surgery will leave me incontinent.

Modern surgeons choose the technique carefully precisely to protect the muscles that control continence. Done by an experienced surgeon, the aim is to cure the fistula while keeping that control — far safer than years of untreated infection.

Diagnosing a fistula starts with a careful look, and sometimes an imaging test to map exactly where the tunnel runs. Costs below are rough India ranges and vary a lot by city, hospital and lab.

The tests

• Clinical examinationa surgeon often diagnoses a fistula by examining the area; this is the first and main step, part of an OPD visit.
• MRI fistulogrammaps a complex or deep tunnel before surgery, roughly ₹6,000–12,000, used when the track is complicated or has branched.
• Endoanal ultrasoundanother way to map the tract from inside, where available, often in a similar range.

The surgery options (named simply, not as advice)

• Fistulotomythe tunnel is laid open to heal from inside out — common for simple, low fistulas.
• Setona thread is placed through the tunnel to drain it and protect the muscle, sometimes as a first stage.
• LIFT and laser (and similar)muscle-sparing techniques chosen for tracks that pass through more muscle.

Cost for surgery in India ranges widely — roughly ₹25,000 to over ₹1,00,000 depending on technique, hospital and complexity. The single smartest move is not picking a procedure from the internet; it is letting a surgeon examine you, map the tract, and match the method to your specific fistula.

Step back, and a fistula is one of those conditions where shame does more damage than the disease. People hide it for months, even years, embarrassed to describe pus near the anus, quietly working through tubes of the wrong cream. Understanding what is really happening changes that: this is a structural plumbing problem, a tunnel from a blocked gland, and naming it honestly is what finally points you toward the one thing that works.

The deeper lesson is that some problems are simply not built to heal themselves, no matter how patient or clean you are. A fistula keeps a doorway open to infection, so it will keep returning until that doorway is properly closed. Recognising this is not defeat — it is what saves you from the long-term grind of repeated abscesses, growing tracks and ongoing discomfort.

What makes this story hopeful is how treatable it is once it is named. For most simple fistulas, surgery is minor, often day-care, and curative — and modern muscle-sparing techniques mean the fear of losing control is far smaller than the old stories suggest. The future here is genuinely good: people get fully better and stop organising their lives around a leaking wound.

The small first step matters most. Put down the piles cream, stop waiting for it to heal on its own, and book a visit with a colorectal or general surgeon. One honest conversation with the right doctor does more than a year of hiding ever will.
