Pilonidal Sinus

Summary about Disease


A pilonidal sinus is a small hole or tunnel in the skin, often located in the cleft between the buttocks. It can become infected and filled with pus or debris, leading to pain, swelling, and discomfort. It's more common in young men and those who sit for prolonged periods.

Symptoms


Pain, especially when sitting

Swelling

Redness

Drainage of pus or blood

Foul odor

A small pit or sinus on the skin's surface

Tenderness to the touch

Causes


The exact cause isn't fully understood, but several factors are believed to contribute:

Loose hairs penetrating the skin

Friction and pressure (e.g., prolonged sitting)

Ingrown hairs

Hormonal changes

Excessive sweating

Deep natal cleft

Medicine Used


Antibiotics: To treat infection. (e.g., cephalexin, clindamycin)

Pain relievers: Over-the-counter or prescription to manage pain. (e.g., ibuprofen, acetaminophen)

Topical antiseptics: To cleanse the area.

Surgical Treatment: To remove the sinus.

Is Communicable


No, a pilonidal sinus is not communicable or contagious. It is not caused by a virus or bacteria that can be spread from person to person.

Precautions


Maintain good hygiene, especially in the affected area.

Keep the area clean and dry.

Avoid prolonged sitting.

Use a cushion if you must sit for long periods.

Hair removal (shaving, waxing, laser) around the affected area may help.

Weight management if overweight or obese.

How long does an outbreak last?


The duration of a pilonidal sinus outbreak can vary:

Acute infection: A few days to a couple of weeks with treatment (antibiotics, drainage).

Chronic condition: Can persist for months or years with intermittent flare-ups if not properly treated with surgical intervention.

How is it diagnosed?


Physical Examination: A doctor can usually diagnose a pilonidal sinus based on a visual examination of the area.

Medical History: The doctor will ask about your symptoms and medical history.

Imaging (Rare): In some cases, imaging tests like an MRI may be used to assess the extent of the sinus tract.

Timeline of Symptoms


Early Stages: May start with a small, painless pit.

Progression: The area becomes inflamed, swollen, and painful.

Infection: Pus and blood drainage may occur.

Chronic Stage: Intermittent flare-ups and drainage can persist if untreated.

Important Considerations


Early treatment is important to prevent complications.

Surgery may be necessary for recurrent or chronic cases.

Post-operative care is crucial for healing and preventing recurrence.

Individuals with a deep natal cleft or excessive hair growth may be more prone to developing a pilonidal sinus.
