A pilonidal sinus (PNS) is a small cyst or abscess that occurs in the cleft at the top of the buttocks. A PNS usually contains hair, dirt, and debris. It can cause severe pain and can often become infected. If it becomes infected, it may ooze pus and blood and have a foul odor.
A PNS is a condition that mostly affects men and is also common in young adults. It’s also more common in people who sit a lot, like cab drivers.
Causes of pilonidal cyst
It may be present at birth;
A hair follicle becomes stretched, or irritated during an exercise while putting pressure on that area such as cycling, or horseback riding;
Trapped loose hair in the crease of the buttock and poke the skin which can cause infection.
What are the symptoms?
Once the cyst becomes infected, the area will swell and these symptoms can occur:
- Bad smell coming from the pus;
- Pus or blood leaking from the opening of the skin;
- Reddening of the area.
The first thing that needs to be done is to drain the cyst and this can be done in the office. You’ll also be prescribed antibiotics in case the infection is severe. If the worst cases, you’ll need surgery to remove it and it may be done as an outpatient procedure, or in the hospital. The procedure will take more than a month to heal.
In case you have a cyst that does not cause any symptoms or if you’ve had a procedure in order to get rid of it, you will have to keep the area dry and clean, and also not to seat on hard surfaces for longer periods of time.
