If you notice two or more small holes, pits, or openings in the cleft between your buttocks, you may wonder whether they are separate problems or different parts of the same pilonidal sinus.
Multiple openings are a common feature of pilonidal disease. They may occur when several pits are present or when inflammation and recurrent disease lead to interconnected sinus tracts beneath the skin.
So, why does pilonidal sinus have multiple openings?
A pilonidal sinus can have multiple openings because pilonidal disease may involve several pits and interconnected channels beneath the skin. Trapped hair, skin debris, friction, inflammation, and recurrent infection can contribute to the development and persistence of these openings.
Multiple openings do not automatically mean that the condition is severe. However, several openings accompanied by recurrent drainage, swelling, pain, or abscess formation may indicate more extensive pilonidal disease and should be evaluated by a specialist.
Pilonidal sinus openings are small pits or holes that develop in or around the natal cleft, usually close to the tailbone.
They may appear as:
Some openings may be connected to sinus tracts beneath the skin.
One opening may remain inactive, while another may periodically release fluid or pus. The appearance can vary depending on whether the disease is currently inflamed or inactive.
Pilonidal disease can involve multiple pits and sinus tracts rather than a single opening.
When hair or debris becomes embedded in the natal cleft, the surrounding tissue may become irritated and inflamed. Over time, sinus tracts can develop beneath the skin, and additional openings may appear.
The openings may be:
Therefore, multiple pilonidal sinus openings may represent different parts of the same underlying disease rather than several completely separate conditions.
Yes.
Pilonidal disease may initially appear as a single small pit. If the condition persists or repeatedly becomes inflamed, additional pits or external openings may become noticeable.
Repeated inflammation, drainage, and formation of sinus tracts can contribute to a more extensive pattern of disease.
A possible progression is:
Small pit → inflammation → drainage → persistent sinus tract → additional pits or openings
This is one reason recurrent pilonidal disease should be evaluated rather than simply treated each time symptoms temporarily improve.
Not necessarily.
A person can have multiple pilonidal pits without having an active infection at that particular time.
However, infection or significant inflammation becomes more likely when the openings are accompanied by:
A painful, swollen lump near the openings may indicate a pilonidal abscess and should be medically assessed.
Yes.
If multiple openings are connected to underlying sinus tracts, fluid or inflammatory material may drain through one or more of them.
You may notice:
Drainage can stop temporarily and then return if an opening becomes blocked or inflammation develops again.
This explains why some people experience periods of improvement followed by another episode of swelling or discharge.
A pilonidal sinus opening can sometimes close temporarily even though the underlying tract remains.
When the external opening closes, fluid and inflammatory material may become trapped beneath the skin. This can cause pressure and swelling.
You may then experience:
The opening may later reopen and release fluid or pus.
This can create a recurring cycle:
Opening closes → fluid accumulates → swelling develops → opening reopens → drainage occurs → symptoms temporarily improve
Therefore, a pilonidal opening closing does not necessarily mean that the underlying sinus has healed.
Hair is considered an important factor in the development and persistence of pilonidal disease.
Loose or broken hairs can become embedded in the natal cleft. Friction, pressure, moisture, and local skin conditions may contribute to inflammation and sinus formation.
Once a sinus has developed, additional hair and debris may contribute to continued irritation.
After the area has completely healed, a healthcare professional may recommend appropriate hair-management strategies depending on the individual’s risk of recurrence.
Do not shave, wax, or use chemical hair-removal products on an open or healing wound unless specifically advised by a healthcare professional.
Not necessarily.
The number of visible openings alone does not determine how difficult pilonidal disease will be to treat.
A specialist may need to assess:
The anatomy beneath the skin is particularly important when determining the most appropriate treatment approach.
Someone with several superficial pits may have less extensive disease than someone with fewer openings but deeper or more complex sinus tracts.
Some pilonidal pits can remain inactive for long periods, and symptoms may temporarily disappear.
However, if an established sinus is repeatedly causing swelling, pain, or drainage, spontaneous and permanent healing should not be assumed.
An external opening may close while the underlying sinus tract remains.
If the same area repeatedly becomes swollen, painful, or starts draining again, specialist evaluation can help determine whether persistent pilonidal disease is present.
If you notice multiple pits or openings around the tailbone, consider having them evaluated, particularly when they are associated with symptoms.
You develop severe pain, rapidly increasing swelling, fever, chills, spreading redness, or feel significantly unwell.
These symptoms may indicate an acute abscess or more significant infection requiring timely assessment.
Diagnosis usually begins with a physical examination of the natal cleft.
A doctor may examine the area for:
In many cases, pilonidal disease can be diagnosed clinically.
Additional imaging may sometimes be considered when the disease is recurrent, extensive, atypical, or when the underlying anatomy is unclear.
Understanding the location and extent of sinus tracts can be important when planning treatment.
Treatment depends on the nature and extent of the disease.
An asymptomatic pilonidal pit may not require the same approach as an actively infected abscess or recurrent sinus.
An acute pilonidal abscess may require appropriate drainage to remove the collection of pus.
Additional treatment may be considered depending on the extent of infection and the individual’s symptoms.
Persistent or recurrent pilonidal disease may require a procedure designed to address the affected sinus tracts.
Depending on the individual case, treatment approaches may include minimally invasive procedures or surgical techniques.
The appropriate treatment is determined by factors such as:

So, why does pilonidal sinus have multiple openings?
Multiple openings can develop when pilonidal disease involves several pits or interconnected sinus tracts beneath the skin. Trapped hair and debris, friction, inflammation, and recurrent episodes of infection can contribute to the development and persistence of these openings.
Having multiple openings does not automatically mean that the condition is severe. However, recurrent drainage, swelling, pain, or abscess formation may indicate more extensive or persistent pilonidal disease.
If you notice several pits or openings near the tailbone, particularly if they repeatedly drain or become swollen, professional evaluation can help determine the extent of the condition and the most appropriate treatment approach.
