How is pilonidal disease diagnosed?
Your doctor will begin by doing a full physical examination. A pilonidal infection should be visible by the naked eye. The doctor may see what looks like a pimple or oozing cyst. He or she may also ask you several questions, including:
- Whether the cyst or pimple has changed in appearance
- Whether it is draining fluid
- Whether you have any other symptoms
Rarely, a CT scan may be ordered to look for sinus cavities under the surface of the skin.
