Pilonidal Sinus

The pilonidal cyst is a cyst that forms in the lower back area, known in Arabic as the “Aseesa” area. This cyst may contain hair, dead skin, or both. The primary cause is the presence of a hole in the hair that is still growing in this area. This condition usually affects young people, especially those who sit for long periods of time, such as drivers, programmers, or office workers.

Causes of pilonidal cysts

The movement and irritation of skin layers essentially cause pilonidal cysts, leading to hair penetrating the skin and forming a cyst. Other factors can include:

  • excessive friction between the skin and clothing, as well as excess body weight.
  • riding bicycles or wearing tight clothing.
  • poor sitting posture, which creates pressure on the affected area, and prolonged sitting can certainly lead to pilonidal cysts.

Symptoms of pilonidal cysts 

The symptoms of pilonidal cysts are usually quite clear and can be distinguished from anal fistulas. Patients with pilonidal cysts typically start by feeling discomfort in the lower back area (the “Aseesa”). A stage of skin irritation and severe pain is experienced when sitting or moving.

The irritated skin in this stage is highly sensitive and can lead to intense itching in the lower back area. This itching can cause the skin to break open, allowing blood and foul-smelling pus to escape from the pilonidal cyst’s opening.

Treatment for pilonidal cysts can be done through various methods, including laser treatment.

Preventing pilonidal cysts involves maintaining personal hygiene, avoiding excessive weight gain, avoiding prolonged sitting, and paying attention to hair removal in that area, especially for those who have had pilonidal cysts before.
