Patients Come to Dr. Nasseri in Pain — and Leave Free of It
Most patients arrive after months or even years of discomfort: recurring flare-ups, painful sitting, drainage that keeps coming back after every lancing. Dr. Nasseri has heard every version of this story — and has a proven answer to it.
The pain of a pilonidal flare-up is unlike anything else — a deep, throbbing pressure at the tailbone that turns everyday life into a series of calculations. How long is the drive? How hard is the chair? Will sitting through a meeting, a class, or a flight make it worse? Many of our patients tell us they quietly rearranged their whole lives around their cyst — skipping the gym, avoiding travel, sleeping on their side, dreading every recurrence.
And because of where pilonidal disease occurs, too many people suffer in silence — embarrassed to talk about it, hoping it will go away on its own. It rarely does. Flare-ups tend to return, each one more disruptive than the last.
You don’t have to live this way. Pilonidal disease is completely treatable — and with the right surgical technique, it almost never comes back.
