What is Pilonidal sinus: Causes, Symptoms and Treatment Options

Ever wonder about Pilonidal sinus and what causes it? This common yet often misunderstood condition can be painful and frustrating, but understanding what is Pilonidal sinus, its causes, symptoms, and treatment options can help you manage and prevent it effectively. With the right knowledge and care, you can take control of your health and avoid future complications.

What is Pilonidal Sinus? 

Pilonidal sinus (PNS) is a common but often misunderstood condition that affects the area near the tailbone (coccyx). It is characterized by a small cyst or tunnel in the skin that can become infected and filled with pus, leading to discomfort and pain. This condition predominantly affects young adults, particularly men, and is often associated with prolonged sitting, excessive hair growth, and poor hygiene. Understanding its causes, symptoms, and treatment options is essential for effective management and prevention.

Causes of Pilonidal Sinus 

The exact cause of Pilonidal sinus is not entirely clear, but several factors contribute to its development. Below are some common Causes of Pilonidal Sinus that may lead to discomfort, infection, and potential complications.

  1. Ingrown Hair: One of the primary causes of Pilonidal sinus is hair penetration into the skin, leading to inflammation and infection. 
  2. Friction and Pressure: Continuous pressure or friction in the sacrococcygeal region, commonly due to prolonged sitting or tight clothing, can contribute to the condition. 
  3. Poor Hygiene: Lack of proper hygiene can lead to bacterial growth, increasing the risk of infection. 
  4. Genetic Factors: Some individuals may have a genetic predisposition to developing pilonidal sinus due to hair type or skin structure. 
  5. Obesity: Excess weight increases pressure on the lower back and buttock area, making it easier for hair to be pushed into the skin. 
  6. Increased Sweating: Excessive sweating in the area can cause skin irritation, making it more susceptible to infection. 

Symptoms of Pilonidal Sinus 

The signs and symptoms of Pilonidal sinus can vary depending on the severity of the condition, ranging from mild discomfort to severe infection. Recognizing Pilonidal sinus symptoms early can help in timely treatment and prevention of complications. Some common signs to watch for include:

  • A small dimple, lump, or cyst near the tailbone 
  • Pain and tenderness in the affected area 
  • Swelling and redness around the cyst 
  • Formation of pus or blood-filled abscess 
  • Foul-smelling drainage from the sinus 
  • Fever and fatigue in case of severe infection 


If left untreated, pilonidal sinus can lead to chronic infection and recurrence, causing significant discomfort and requiring medical intervention. Book a consultation today with a trusted Pilonidal Sinus doctor in PCMC.

Pilonidal Sinus Treatment Options

Pilonidal Sinus Treatment Options depend on the severity of the condition, ranging from home remedies to surgical procedures. Early diagnosis and proper care can help in effective management. Below are some primary treatment options for Pilonidal Sinus:

1. Conservative Treatment 

For mild cases, non-surgical approaches may be effective, including: 

  • Antibiotics: To control infection, though they may not eliminate the sinus entirely. 
  • Warm Compresses: Applying heat can reduce pain and inflammation. 
  • Good Hygiene Practices: Keeping the area clean and dry to prevent bacterial growth. 
  • Hair Removal: Regular shaving or laser hair removal can help reduce recurrence.

2. Drainage and Incision 

For cases involving abscess formation, a doctor may perform a minor procedure to drain pus and relieve pain. This helps reduce inflammation and promotes healing while lowering the risk of further infection.

3. Surgical Treatment 

When pilonidal sinus becomes recurrent or severe, surgery may be necessary. The main surgical approaches include: 

  • Excision and Open Healing: The infected tissue is removed, and the wound is left open to heal naturally with regular dressing changes. 
  • Excision and Primary Closure: The sinus is removed, and the wound is stitched closed for faster healing. 
  • Flap Surgery: In complex cases, surrounding tissue is used to close the wound and reduce recurrence risk. 

How to Prevent Pilonidal Sinus?

Pilonidal sinus prevention focuses on maintaining healthy skin and making lifestyle adjustments to lower the risk of recurrence. Simple daily habits, along with proactive care, can make a significant difference. Some effective ways to prevent Pilonidal sinus include:

  • Maintaining Proper Hygiene: Keeping the area clean and dry reduces bacterial growth. 
  • Regular Hair Removal: Shaving or laser hair removal can prevent ingrown hairs. 
  • Avoiding Prolonged Sitting: Taking breaks from sitting for long periods reduces pressure on the tailbone. 
  • Wearing Loose, Breathable Clothing: Prevents friction and excessive sweating. 
  • Maintaining a Healthy Weight: Reducing excess weight can decrease pressure on the sacrococcygeal area.
