The most common pilonidal sinus symptoms are pain, swelling and a small pit or lump near the tailbone, often with pus or blood draining from the skin. These signs usually appear at the top of the buttock crease and worsen with sitting or infection. Recognising them early helps you avoid painful abscesses and repeated flare-ups. This article explains what a pilonidal sinus is, the key early warning signs to watch for, other causes, complications, and the diagnosis and treatment options available at Lux Hospitals so you can act quickly.
What Is a Pilonidal Sinus?
A pilonidal sinus is a small tunnel or cavity in the skin at the top of the buttock crease, near the tailbone. It often contains hair, debris and skin cells.
When this cavity becomes blocked or infected, it can form a painful abscess. It mostly affects young adults, especially men who sit for long hours.
Common features include:
- Small pit or dimple in natal cleft
- Trapped hair inside the tract
- Tendency to recur if untreated
- More common in hairy individuals
- Linked to prolonged sitting

1. Pain and Tenderness Near the Tailbone
Pain at the top of the buttock crease is usually the first pilonidal sinus symptom people notice. It often feels worse when sitting, bending or standing up.
The area may feel tender or throbbing, especially during an infection.
Typical pain patterns include:
- Sharp pain while sitting
- Throbbing during a flare-up
- Discomfort when standing from a chair
- Tenderness on gentle touch
- Pain worsening over days
Don't ignore tailbone pain—book an evaluation at Lux Hospitals.
2. Swelling and a Lump
A soft or firm lump often develops over the sinus, signalling fluid or pus buildup. This swelling can grow quickly during an active infection.
The lump may feel warm and increasingly painful.
You may notice:
- A visible bump near tailbone
- Rapidly enlarging swelling
- Firmness under the skin
- Warmth over the lump
- Pressure that eases after drainage
3. Pus or Blood Drainage
Drainage of pus or blood from a small opening is a clear sign the sinus is infected. The fluid may stain clothing or bedding.
Drainage sometimes brings temporary relief from pressure and pain.
Drainage clues include:
- Yellow or cloudy pus
- Blood-streaked discharge
- Foul-smelling fluid
- Staining on underwear
- Recurring leakage from the pit
Persistent drainage needs prompt attention—consult the specialists at Lux Hospitals.
4. A Visible Pit or Opening
Many people notice one or more tiny pits or holes in the skin along the buttock crease. These openings mark where the sinus tract reaches the surface.
Hair may sometimes be seen poking out of these pits.
Signs to look for:
- Small dimple or hole
- Multiple openings in a line
- Hair protruding from a pit
- Dark spots along the crease
- Opening that intermittently discharges
5. Skin Redness and Warmth
Inflamed skin around the sinus often turns red and feels warm to the touch. This indicates the body is fighting an infection.
The redness may spread as the infection worsens.
Watch for these skin changes:
- Redness around the opening
- Warm, inflamed skin
- Shiny, stretched appearance
- Spreading discolouration
- Increased tenderness with redness
6. Fever and Foul Odour
When infection advances, you may develop a low-grade fever and general tiredness. A foul smell from the draining fluid is also common.
These systemic signs suggest an abscess needing urgent care.
Advanced infection symptoms include:
- Mild to moderate fever
- Fatigue or feeling unwell
- Foul-smelling discharge
- Increasing pain and swelling
- Chills during a severe flare
Fever with tailbone swelling needs urgent review—reach out to Lux Hospitals now.
Other Causes and Risk Factors
Several factors raise the risk of developing a pilonidal sinus. Understanding them helps with prevention and early detection.
Symptoms can sometimes mimic other conditions like an anal fistula or a perianal abscess, so a proper exam matters.
Common risk factors include:
- Prolonged sitting or driving
- Excess body hair
- Being overweight
- Poor hygiene in the area
- Friction from tight clothing
- Family history of the condition
Complications of Untreated Pilonidal Sinus
Ignoring symptoms can lead to repeated infections and worsening tunnels under the skin. Early treatment prevents these problems.
Chronic cases may cause long-term discomfort and scarring.
Possible complications include:
- Recurring painful abscesses
- Multiple branching sinus tracts
- Chronic wound drainage
- Skin scarring and thickening
- Rarely, long-standing skin changes
Avoid complications by treating pilonidal sinus early at Lux Hospitals.
How a Pilonidal Sinus Is Diagnosed
Diagnosis is usually straightforward and based on a physical examination of the buttock crease. Your specialist inspects the pits, swelling and any drainage.
Imaging is rarely needed but may be used for complex or recurrent cases.
Diagnosis typically involves:
- Visual exam of the natal cleft
- Checking for openings and hair
- Assessing signs of infection
- Reviewing symptom history
- Imaging for complicated cases
