Pilonidal Cyst

Jason Rivera is a 21-year-old male presenting with painful lump at tailbone. About a week ago, I started feeling some soreness right at the top of my butt crack, near my tailbone. At first I thought I'd just bruised it from sitting too long — I drive a delivery van for work and I also sit a lot studying. But then a definite lump started forming and it's been getting bigger and more painful every day. Your task is to take a focused history from this patient.
