“Doctor, there’s a small painful boil near my tailbone. It heals, then comes back again. I’ve had three antibiotic courses this year — what’s actually wrong?”
This is one of the most common stories I hear in clinic, especially from young men in their twenties and thirties working long desk-bound jobs in Pune’s IT corridor. Most of them have already been treated for “boils” or “abscesses” two or three times. What they actually have is a pilonidal sinus — a small tunnel under the skin near the tailbone that keeps trapping hair and infection. Without proper pilonidal sinus treatment, it returns again and again.
The good news? Modern, minimally invasive pilonidal sinus laser treatment can shut down this cycle in a single day-care procedure — with very little pain and a quick return to work. This guide explains what pilonidal sinus is, why it forms, how to recognise the symptoms, and exactly how we treat it at Sharvari Hospital, Pune.
I’m Dr. Kundan Kharde (MBBS, MS — General Surgery, FMAS), a senior surgeon with 19+ years of experience. Pilonidal sinus is one of the most under-diagnosed and over-recurring problems I see — let’s fix that for you.
What Is a Pilonidal Sinus?
A pilonidal sinus is a small tunnel or cavity under the skin in the natal cleft — the deep groove between the buttocks, just above the tailbone. The Latin word “pilonidal” literally means “nest of hair” — and that’s exactly what it is. Loose body hair gets pushed into the skin, the body treats it as a foreign body, and a chronic infected tunnel forms.
Pilonidal disease is most common in:
- Men aged 15–35 (about 3–4 times more than women)
- People with thick or coarse body hair
- Long-distance drivers, IT professionals, and students who sit for long hours
- Those who are overweight or sweat heavily
- People with a deep natal cleft
It is not a sexually transmitted disease, it is not caused by poor hygiene, and it is not related to piles, fissure, or fistula — although it is often confused with anal fistula. (For a side-by-side comparison, see our guide on pilonidal sinus vs anal fistula.)
What Causes Pilonidal Sinus?
The main mechanism is hair burrowing into the skin of the natal cleft, where it triggers a foreign-body reaction and chronic infection. Several factors push this along:
- Friction and pressure from prolonged sitting (cars, bikes, office chairs, study tables)
- Sweating and moisture in the cleft, which softens skin and lets hair penetrate
- Tight clothing that traps hair against the skin
- Excess body weight that deepens the natal cleft
- Family history — some people inherit a deeper, narrower cleft
- Hormonal activity in the late teens and twenties, which thickens body hair
- Prior trauma — even a minor knock to the tailbone can start the process
Once hair enters the skin, the body forms a small cavity around it. Over weeks or months, more hair, dead skin cells, and bacteria collect inside. Eventually it forms an abscess — that “boil” the patient first notices.
Pilonidal Sinus Symptoms — What to Look For
Symptoms range from a tiny dimple no one notices to a painful infected cavity that stops the patient from sitting. The most common pilonidal sinus symptoms are:
- A small pit or dimple in the midline above the tailbone (often the only sign in early cases)
- Pain or tenderness while sitting, cycling, or driving
- Swelling and redness near the tailbone
- Pus or blood discharge from one or more small openings — sometimes with a foul smell
- Recurrent boils or abscesses in the same area that “keep coming back”
- Fever or chills when an acute abscess forms
- Visible hair sticking out of the sinus opening in some patients
Many patients describe a “healing-and-bursting cycle”: the area gets painful and swollen, drains pus on its own (or is drained by a doctor), feels better for a few weeks, and then breaks down again. That cycle is the classic clue that this is not a simple boil — it’s an underlying sinus tract that needs definitive pilonidal sinus treatment.
How Pilonidal Sinus Is Diagnosed
In most cases, diagnosis is clinical — a careful examination of the natal cleft is enough. As your surgeon, I look for:
- The midline pits — usually one to several tiny openings on the centreline above the tailbone
- Secondary openings off to one side (where the tunnel exits)
- Signs of an acute abscess — warmth, redness, fluctuant swelling
- The extent of the tract — felt with a gentle probe in clinic
In complex or recurrent cases, an MRI of the sacrococcygeal area helps map the full tract before surgery. We rarely need a CT scan. If the picture is unclear and the tunnel appears to extend toward the anal area, we may also do a careful proctology exam to rule out an anal fistula.
A correct diagnosis matters because the wrong surgery can give you a long, painful, non-healing wound. This is why I urge patients not to settle for “let’s just cut it open and see” at a clinic that does pilonidal sinus surgery once a month.
Pilonidal Sinus Treatment Options
Treatment depends on whether the disease is acute (a hot, infected abscess) or chronic (a draining sinus that keeps coming back). Here are the main options, in order of how invasive they are.
1. Conservative Care for Very Early Disease
If you have only a small, asymptomatic pit with no pain or discharge, you may not need surgery yet. Hygiene measures — keeping the area dry, avoiding tight clothing, regular shaving or laser hair reduction over the cleft, and weight control — can keep the disease silent for years. But once it has been infected even once, surgery is usually the long-term answer.
2. Incision and Drainage (Emergency Step)
If you walk in with an acute abscess — a hot, painful swelling — the first step is simply to drain the pus under local anaesthesia. This gives instant relief but it does not cure the underlying sinus. About 60% of these abscesses recur within a year unless definitive surgery is done. Think of it as putting out the fire — you still need to fix the wiring.
3. Pilonidal Sinus Laser Treatment (Our Preferred Approach)
For most patients with chronic pilonidal sinus, laser treatment — also called SiLaC (Sinus Laser Closure) or laser-assisted pilonidal sinus surgery — is the most patient-friendly option available today. Here’s how it works:
- Done as a day-care procedure under spinal or short anaesthesia
- A fine laser fibre is passed into the sinus tract through the existing opening
- The laser delivers controlled energy that destroys the lining of the tract and seals it from the inside
- No large incision, no big open wound, no flap surgery
- Typical procedure time: 20–30 minutes
- Stitches are usually not needed; only a small dressing
- Most patients walk out the same day and return to desk work within 3–5 days
Why we like it for IT professionals, drivers, and students in Pune: very little time off work, almost no scar, and a much lower wound-care burden than the older “open wide and pack daily” approach.
Laser pilonidal sinus treatment works best for uncomplicated, single-tract sinuses without major branching. For more complex disease, we may combine laser with a minimally invasive flap technique to give the cleft a flatter shape and reduce recurrence.
4. Minimally Invasive Surgical Options
When the disease is more extensive or recurrent, we offer:
- Pit-picking (Bascom procedure) — tiny excisions of the midline pits with a small lateral drainage incision; very low downtime
- Endoscopic Pilonidal Sinus Treatment (EPSiT) — a small camera and instruments are passed inside the tract to clean it out under direct vision
- Karydakis or Limberg flap surgery — the cleft is reshaped so hair can no longer enter; reserved for recurrent or wide disease
Each of these has trade-offs in scar size, recurrence rate, and time off work. The right choice is matched to your anatomy, not to the surgeon’s habit. (For a broader patient-side comparison, read our minimally invasive vs traditional surgery guide.)
5. Traditional Wide Excision and Open Healing
The oldest method — cutting out the entire diseased tissue and leaving the wound open to heal slowly with daily dressings — is still done in some hospitals. It works, but it means 6–8 weeks of dressings, time off work, and a deeper scar. We rarely recommend it as first-line treatment when laser or flap options are suitable.
Recovery and Lifestyle Tips
What recovery looks like after pilonidal sinus laser treatment at Sharvari Hospital:
- Day 0 — discharge home the same evening with mild oral painkillers
- Day 1–2 — mild soreness while sitting; walking is encouraged
- Day 3–5 — most desk-job patients are back at work, often part-time first
- Week 2 — driving, light exercise, and most office activities resume
- Week 4–6 — full healing; resume gym, cycling, and long-distance travel
Daily lifestyle steps that protect against recurrence:
- Keep the cleft hair-free — regular trimming, shaving, or laser hair reduction every 4–8 weeks for at least a year after surgery
- Stand up every 45–60 minutes if you sit for work; it relieves pressure on the cleft
- Shower daily, dry the area thoroughly, and avoid sitting in damp gym clothes
- Wear loose, breathable underwear and trousers
- Maintain a healthy weight to reduce cleft depth and friction
- Stay hydrated and eat fibre-rich food — softer stool means less straining and less pressure on the area
- Do not pick at scabs or pits, even if you see a hair tip emerging
Recurrence after correctly performed laser or flap surgery, combined with good aftercare, is typically below 10% in our clinic experience — much lower than after simple incision and drainage alone. If you are reading this because a previous operation has already failed, see why a pilonidal sinus comes back and what should be done next.
When Should You See a Doctor?
Don’t wait for the third or fourth flare-up. Book a proctology consultation if you notice:
- A persistent painful swelling near the tailbone
- Pus, blood, or foul discharge from a small opening above the buttocks
- Recurrent boils in the same spot — even if they “burst and feel better”
- A non-healing wound or sinus from a previous surgery elsewhere
- Fever with severe pain — this can indicate an acute abscess that needs same-day drainage
- A small midline pit you’ve had for years that’s now starting to discharge
The sooner pilonidal disease is treated, the simpler, less painful, and less expensive the surgery is. Long-neglected sinuses become multi-tract, infected, and harder to close.

Frequently Asked Questions (FAQ)
Is pilonidal sinus a serious condition?
It’s not life-threatening, but it is chronic and recurrent. Untreated pilonidal sinus can lead to repeated abscesses, painful flares, time off work, and — very rarely, after decades of neglect — skin changes. With correct pilonidal sinus treatment, it can be cured in a single procedure for most patients.
Is pilonidal sinus laser treatment painful?
Most patients report mild soreness for 2–3 days, well controlled with simple painkillers. There is no large open wound and no daily packing. Compared to the traditional wide excision, laser pilonidal sinus surgery is dramatically less painful.
How long does recovery take after laser pilonidal sinus surgery?
Most desk-job patients return to work in 3–5 days. Driving and light exercise are usually fine within 2 weeks. Complete healing takes about 4–6 weeks. Recovery is faster than open excision (which can take 6–8 weeks of dressings).
Can pilonidal sinus come back after surgery?
Recurrence rates depend on the technique and aftercare. With laser or flap surgery plus good lifestyle measures (hair removal, weight control, no prolonged sitting), the recurrence rate is typically under 10% in our experience. With simple incision and drainage alone, recurrence is much higher. If your sinus has already returned after an earlier operation, read our dedicated guide on recurrent pilonidal sinus after failed surgery — the right redo procedure is chosen very differently from a first operation.
Can pilonidal sinus heal without surgery?
A truly asymptomatic pit may stay quiet for years with hygiene measures alone. But once it has been infected, antibiotics only buy temporary relief — they do not close the underlying tunnel. For a chronic, draining, or recurrent pilonidal sinus, definitive surgery is the only real cure.
How much does pilonidal sinus laser treatment cost in Pune?
Costs vary based on the technique, anaesthesia, and your insurance. At Sharvari Hospital, we provide a written, itemised package quote at consultation that includes surgeon’s fee, OT, anaesthesia, room, and follow-up. Most laser pilonidal procedures are cashless-eligible with major insurers.
Is pilonidal sinus the same as anal fistula?
No. Pilonidal sinus sits in the natal cleft above the tailbone; anal fistula opens near the anus and connects to the anal canal. They look similar to patients but need different surgeries. We’ve written a detailed comparison guide — see pilonidal sinus vs anal fistula.
