If acquired, it may be the enlargement of a simple hair follicle infection or the result of a hair penetrating the skin and causing an infection.
Risk FactorsThe following factors increase your chance of developing a pilonidal cyst:
- Personal or family history of similar problems such as acne , boils, carbuncles, folliculitis, and sebaceous cysts
- Large amounts of hair in the region
- Tailbone injury
- Horseback riding, cycling
- Prolonged sitting

- Painful swelling over your sacrum, which is the area just above your tailbone
