🌿 Overview
A pilonidal cyst forms in the crease at the top of the buttocks, near the tailbone, often containing trapped hair and debris. It can sit quietly or flare into a painful, swollen, sometimes draining abscess. Good hygiene and warm soaks help, but an infected one usually needs medical drainage.
