Pilonidal sinus
A surprisingly common condition that most people have never heard of until it happens to them. Everything here is private, anonymous, and built to help you make sense of what you are dealing with.
At a glance
A pilonidal sinus is a small tunnel or cyst that forms in the skin at the top of the buttock crease, near the tailbone. It can become infected, causing pain, swelling, and drainage. Flare-ups range from a one-time event to a recurring pattern that may need surgical treatment. Our basics guide covers what people typically experience and when to seek care.
Common symptoms people report
- Pain, tenderness, or swelling near the tailbone
- A lump or dimple at the top of the buttock crease
- Drainage of fluid or pus, sometimes with an unpleasant smell
- Discomfort when sitting, especially on hard surfaces
- Redness and warmth over the area during a flare-up
- Symptoms that come and go — quiet periods followed by painful episodes

Read experience →Common questions
Can a pilonidal sinus come back after treatment?
Recurrence is one of the most common concerns people have. Rates vary depending on the type of treatment. Some surgical approaches have lower recurrence rates than others, and ongoing hair removal in the area is widely reported to help reduce the chance of it coming back.
How long does recovery from pilonidal surgery take?
This depends on the type of procedure. Some surgeries leave the wound open to heal gradually, which can take weeks to months. Others close the wound and tend to heal faster. Our surgery recovery guide covers what people commonly report for different approaches.
Is it normal to have drainage between flare-ups?
Some people with a chronic pilonidal sinus notice intermittent drainage even when the area is not acutely infected. This is worth mentioning to your doctor, as it may indicate an ongoing tract that could benefit from treatment.
What can I do to reduce flare-ups?
People commonly report that keeping the area clean and dry, removing hair from around the natal cleft, and avoiding prolonged sitting can help. These measures do not guarantee prevention, but they are widely considered part of ongoing management.
