A pilonidal cyst is a fluid-filled sac that forms just above the crease where the buttocks come together. This cyst can become red, inflamed, and infected. It can also cause pain and make it uncomfortable to sit or lie back.
What are the symptoms of pilonidal cyst?
If the cyst is not infected, it might not cause symptoms. But if the cyst is infected, it can cause pain, redness, and swelling in the area above the crease where the buttocks come together. In some cases, the cyst might burst and drain fluid, blood, or pus.
Should I see a doctor?
Yes, if you have symptoms of a pilonidal cyst, you should see a doctor.
How is a pilonidal cyst treated?
If you have a pilonidal cyst without any symptoms, it probably does not need treatment.
If the cyst is causing symptoms, treatment usually involves either draining the cyst or removing it with surgery. Draining a cyst can usually be done at the office.
To drain a cyst, a doctor or nurse will first numb the area. Then they can cut open the cyst, drain it, and wash it out. In some cases, the doctor might also pack the empty cyst with gauze or packing tape.
