What is Pilonidal Sinus?
A pilonidal sinus is a small hole or tunnel in the skin near the tailbone, just above the buttocks. It can collect hair, dirt, and debris. Over time, this opening can get infected and form a pilonidal cyst. This condition is more common in young adults, especially men, and those who sit for long hours.
Pilonidal Sinus vs. Pilonidal Cyst
These two terms are related but slightly different:
- A pilonidal sinus is a tiny opening or tract under the skin.
- A pilonidal cyst happens when this opening becomes infected and swollen.
A cyst is usually more painful and may fill with pus, requiring treatment.
Causes of Pilonidal Sinus
The exact cause isn’t always known, but the main reasons include:
- Ingrown Hairs: The most common cause is believed to be ingrown hairs. Hair follicles can become trapped under the skin, leading to irritation and infection.
- Friction and Pressure: Prolonged sitting or activities that cause friction in the buttock area can increase the risk.
- Genetic Factors: Some individuals may have a genetic predisposition due to body hair and skin structure.
- Obesity: Excess weight can lead to increased friction and moisture in the affected area.
- Poor Hygiene: Inadequate cleanliness can promote bacterial accumulation and debris, increasing the risk of infection.
In some people, hair and dead skin cells enter the sinus and create an infection.
Symptoms of Pilonidal Sinus
Recognizing the symptoms early can prevent complications.
- Pain and Swelling: Discomfort near the lower spine is common, especially while sitting.
- Redness and Tenderness: The affected area may become inflamed and tender to the touch.
- Drainage: Pus or blood may drain from the sinus, sometimes accompanied by a foul odor.
- Fever: In cases of infection, fever and general malaise may occur.
Sometimes the symptoms may come and go. But once infected, the sinus often needs treatment.
Pilonidal Cyst Prevention
To help prevent pilonidal sinus or cyst, try the following:
- Maintain Proper Hygiene: Keeping the affected area clean and dry is crucial to prevent bacterial accumulation and infection. Regular washing with mild soap and water, followed by thorough drying, can help maintain hygiene.
- Hair Removal: Since ingrown hairs are a common cause of pilonidal sinuses, regular hair removal in the affected area can prevent hair from becoming trapped under the skin. Methods such as shaving or using depilatory creams are commonly recommended.
- Weight Management: Maintaining a healthy weight can reduce friction and pressure in the buttock area, lowering the risk of sinus formation. Weight management through a balanced diet and regular exercise is beneficial.
- Avoid Prolonged: Sitting Taking breaks from prolonged sitting can reduce pressure on the tailbone area, which is a common risk factor for pilonidal sinus. Using cushions or pillows can also help alleviate pressure when sitting is necessary.
- Weight Management: Maintaining a healthy weight can reduce friction and pressure in the buttock area, lowering the risk of sinus formation. Weight management through a balanced diet and regular exercise is beneficial.
- Avoid Prolonged Sitting: Taking breaks from prolonged sitting can reduce pressure on the tailbone area, which is a common risk factor for pilonidal sinus. Using cushions or pillows can also help alleviate pressure when sitting is necessary.
- Wear Comfortable Clothing: Loose-fitting, breathable clothing can minimise friction and irritation in the affected area, reducing the likelihood of sinus formation.
These habits can lower your chances of getting an infection or cyst.
Diagnosis of Pilonidal Sinus
Doctors can usually diagnose a pilonidal sinus by looking at the area and checking for swelling, redness, or discharge.
In more serious cases, the doctor might use an:
- Ultrasound to see beneath the skin
- MRI or CT scan (rarely needed) to check deeper infections
Early diagnosis helps prevent complications and longer recovery time.
Treatment Options for Pilonidal Sinus
Treatment varies based on the severity of the condition and whether an infection is present.
- Non-Surgical Treatments
- Antibiotics: Used to treat infections, though they do not eliminate the sinus itself.
- Home Remedies: Warm compresses and sitz baths can provide temporary relief.
- Surgical Treatments
- Incision and Drainage: A common procedure for infected abscesses, where the pus is drained.
- Excision and Healing by Secondary Intention: The sinus is removed, and the wound is left open to heal naturally.
- Minimally Invasive Techniques: Procedures like laser therapy and endoscopic treatment are gaining popularity due to quicker recovery times

Pilonidal Sinus Complications
Pilonidal sinus, while not life-threatening, can lead to several complications if not managed properly. Understanding these complications is crucial for effective management and prevention of further issues.
- Infection and Abscess Formation: One of the most common complications of a pilonidal sinus is infection, leading to the formation of a pilonidal abscess. This occurs when the sinus becomes filled with pus, causing pain, swelling, and redness in the affected area.
- Chronic Discomfort and Pain: The recurrent nature of pilonidal sinuses can lead to ongoing discomfort and pain, significantly affecting an individual's quality of life. This chronic pain can be exacerbated by activities such as sitting or standing for long periods.
- Cellulitis: Infection can spread to the surrounding skin, causing cellulitis. This condition is characterised by redness, warmth, and swelling of the skin, often requiring antibiotic treatment.
- Recurrence: Recurrence is a significant issue with pilonidal sinuses. Even after surgical treatment, the sinus can recur if all sinus tracts are not adequately removed or if hair and debris continue to accumulate in the area.
- Wound Infection Post-Surgery: After surgical intervention, there is a risk of wound infection. Signs include severe pain, inflamed and swollen skin, fever, and pus or blood seeping from the wound site.
Managing Complications
To manage complications:
- Keep the area clean and dry
- Follow your doctor’s advice carefully
- Attend all follow-up visits
- Avoid sitting too long
- Take pain medication as advised
- Avoid heavy activity until healing is complete
If the sinus returns often, further treatment may be needed.
