What are the symptoms of a pilonidal cyst?
A pilonidal cyst may not have any symptoms besides a small pit or dimple on the skin. However, sometimes pilonidal cysts become infected. When this happens, the cyst can become a painful abscess—a swollen, inflamed sac filled with pus (a thick, whitish-yellow fluid). Rarely, an infected pilonidal cyst can cause a fever.
