Understanding Pilonidal Cyst
A pilonidal cyst is a painful lump or swelling that forms at the top of the buttocks, just near the tailbone, and is usually caused by hairs or bits of skin getting trapped under the skin. It can become red, swollen, and very sore — and sometimes it fills with pus and needs to be drained. If you notice a painful lump in that area that is getting worse or not going away, it is a good idea to see a doctor so you can get the right treatment and feel better quickly.
Common Symptoms / Concerns for Pilonidal Cyst
When to Seek Professional Care
Book an evaluation with a healthcare provider immediately if you experience or present with:
- Fever above 39°C that does not go down after taking paracetamol
- Rapidly growing or spreading swelling near the tailbone
- Pus or blood leaking from the area
- Severe pain that makes it impossible to sit, walk, or carry out daily activities
- The lump becomes very hard, hot, or extremely tender to touch
- You feel generally unwell, weak, or shivery alongside the swelling
- The area has not improved after a few days of home care
What to Expect During Your Medical Consultation
When you visit the doctor, they will ask you a few simple questions about how long you have had the lump, how much pain you are feeling, and whether you have noticed any discharge or fever. The doctor will then gently examine the area near your tailbone to understand how serious the cyst is — there is no need to feel embarrassed, as this is a very common condition they see regularly. Depending on what they find, they may recommend a small procedure to drain the cyst, prescribe medication, or refer you to a specialist for further care.

Frequently Asked Questions
What causes a pilonidal cyst?
A pilonidal cyst is usually caused by hairs or bits of dead skin getting pushed under the surface of the skin near the tailbone. This can happen due to friction from sitting for long periods, tight clothing, or having a lot of body hair in that area. Once the hair or skin is trapped, the body reacts to it and a painful lump or cyst forms.
Can I treat a pilonidal cyst at home, or do I need to see a doctor?
For mild discomfort, sitting in warm water (a sitz bath) a few times a day can help ease the pain and reduce swelling. However, if the cyst is very painful, growing, leaking pus, or causing fever, you should see a doctor as soon as possible — do not try to squeeze or burst it yourself, as this can make things worse. A doctor can safely drain it and give you the right treatment to help it heal properly.
What are the treatment options for a pilonidal cyst?
The most common treatment is a small procedure where the doctor numbs the area and makes a tiny cut to drain the pus and relieve the pain — this usually brings quick relief. In some cases, especially if the cyst keeps coming back, a minor operation may be needed to remove the cyst completely. Your doctor will discuss the best option for you based on how serious the cyst is.
Can a pilonidal cyst come back after treatment?
Yes, unfortunately a pilonidal cyst can come back, especially if the area is not kept clean and dry or if the root cause — such as ingrown hairs — is not addressed. Following your doctor's advice after treatment, keeping the area clean, and removing hair from the area regularly can help reduce the chance of it returning. If it keeps coming back, your doctor may recommend a more permanent surgical solution.
How can I prevent a pilonidal cyst from forming?
Keeping the area between your buttocks clean and dry is one of the best ways to prevent a pilonidal cyst. Regularly removing hair from the area — by shaving or using hair removal cream — can also help stop hairs from getting trapped under the skin. Try to avoid sitting in one position for too long, and wear loose, comfortable clothing to reduce friction in that area.
