A pilonidal cyst is a small, abnormal pocket or sac that forms in the skin near the tailbone. The cyst may contain hair, debris, or other materials that have become trapped in the skin. If the cyst becomes infected, it can develop into a pilonidal abscess, which is a painful collection of pus in the cyst. A pilonidal sinus is a small channel or tunnel that connects the cyst to the skin's surface.
The exact cause of pilonidal cysts and sinuses is unknown, but some factors increase the risk of developing them. These factors include:
The symptoms of pilonidal cysts and sinuses include:
The treatment for pilonidal cysts and sinuses depends on the severity of the condition. In some cases, the cyst may go away on its own without treatment. However, if the cyst becomes infected, it will need to be drained. This can be done in a doctor's office or hospital setting.
In more severe cases, surgery may be required to remove the cyst and sinus. This is typically done under general anesthesia and involves cutting out the cyst and surrounding tissue. The wound is then closed with sutures or left open to heal.
To prevent pilonidal cysts and sinuses from developing or recurring, it's important to maintain good hygiene and keep the area around the tailbone clean and dry. Avoid sitting for long periods of time, wear loose-fitting clothing, and avoid activities that put pressure on the tailbone.
If you think you may have a pilonidal cyst or sinus, it's important to see a doctor for an accurate diagnosis and appropriate treatment.
