A Pilonidal sinus also called Pilonidal cyst, Pilonidal abscess or Sacrococcygeal fistula is a cyst ( small sac ) or tunnel in the skin. It develops over the tailbone at the top of the cleft of the buttocks. The cyst usually contains hair and skin debris. More than one cyst may develop and these are linked by tunnels under the skin.
TREATMENT:
No treatment is necessary in case of a Pilonidal sinus that lies dormant, which means it is not infected. In this silent phase, certain precautions are advised which may abate the chances of infection and thereby, the need for a surgery. Following care should be taken :
1. Keep the area as clean and dry as possible.
2. Avoid sitting in one place for too long, avoid driving for long hours.
3. Remove hair from the area using a razor or hair removal cream. You could see a dermatologist ( skin specialist ) and consider permanent hair removal with Laser.
