Can a pilonidal cyst go away on its own?

In patients with a pilonidal cyst or sinus, what proportion resolve without surgical intervention, and how long does spontaneous resolution take compared with recurrence after non-operative management?

How people search for this, in their own words

  • “do pilonidal cysts go away”
  • “can a pilonidal cyst go away on its own”
  • “will a pilonidal cyst go away by itself”
  • “how long does it take for a pilonidal cyst to go away”

What the evidence says

Bottom line

A pilonidal cyst can sometimes settle down without surgery, but the evidence for this is extremely thin.

The only study that actually watched an untreated cyst over time is a single case report of a pregnant woman, whose symptoms came and went on their own before she eventually had surgery. Other studies looked at treatments like hair removal, antibiotics, or surgery versus each other — not at what happens if you simply leave a cyst alone — so there is no reliable number for how often cysts resolve by themselves or how long that takes.

How certain

Very low

The only direct evidence is 1 small or uncontrolled study.

What it shows

Possible benefit

The evidence points to a benefit, but it is not strong enough to be confident.

What the research shows

  • Spontaneous resolution rate (cyst goes away with no treatment at all)

    Only one case has been reported in which symptoms resolved without any treatment — and they later came back. This is not enough to give a percentage or a reliable answer.[1]

    Insufficient evidence

  • Time to resolution of symptoms

    No study tracked how long it takes for an untreated cyst to settle down. The one case report does not give a clear timeline either.[1]

    Not studied

  • Recurrence rate after conservative (non-surgical) management

    In two studies, recurrence after non-surgical care (hair removal, in-clinic care) was similar to or lower than after surgery, but the groups compared were not randomly assigned, so this may reflect milder cases being managed without surgery rather than a true benefit.[1,2]

    Possible improvement

  • Progression to abscess requiring drainage

    No study measured how often an untreated cyst turns into a painful abscess that needs draining.

    Not studied

  • Need for eventual surgery after trying non-surgical care

    In small studies of laser hair removal, some patients avoided surgery entirely, and most of those who still needed it were cured with one operation. These studies tested an active treatment, not simply waiting.[1,2]

    Possible improvement

  • Symptom-free interval duration

    No study reported how long symptom-free periods typically last without treatment.

    Not studied

What it may help with

  • In one case report, a pregnant woman's pilonidal symptoms resolved on their own twice, without any treatment, though they returned each time.[1]
  • In young patients who were symptom-free, regular hair removal alone led to a similar recurrence rate as surgery plus hair removal, suggesting that avoiding surgery doesn't necessarily mean worse outcomes for mild cases.[1]

Important limitations

  • There are no randomized trials on this question at all — every study is observational, meaning other differences between groups (not the treatment itself) could explain the results.[1,2,3,4,5,6,7,8]
  • The only study that followed an untreated cyst over time, rather than comparing treatments, is a single case report. One person's experience cannot tell us what usually happens.[1]
  • Most studies tested an active treatment (hair removal, antibiotics, surgery) rather than true watchful waiting with nothing done, so they can't answer whether cysts resolve with no intervention at all.[1,2,3,4]
  • Populations studied were often specific groups — children, military service members, or pregnant patients — which may not reflect the average adult asking this question.[1,2,3]

    Conservative care had fewer recurrences than surgery.RetrospectiveLow qualityRelated question

    69 people2026

    recurrence happened in 26.1% of patients who had surgery versus 2.2% of patients managed without surgery

    Who was studied
    children and teenagers up to 18 years old with pilonidal sinus disease
    What they received
    structured outpatient care including conservative treatment and in-clinic debridement
    Compared with
    operative treatment (trephination or limited excision)
    Main outcome
    recurrence after the wound had healed
    Quality
    This was a single-centre retrospective study where the surgical group likely had more severe disease to begin with, so the comparison may be biased rather than a fair test of treatments.
    Limitations
    Retrospective design, single centre, and the authors note that patients undergoing operative intervention likely represented a more severe subgroup, meaning the groups may not be comparable.

    Management of Pilonidal Disease: A Review

    Reviews treatments, not natural resolution.Narrative reviewLow qualityRelated question

    size not given2023

    review found treatment evidence is limited and of poor quality, with no information on whether cysts resolve without treatment

    Who was studied
    people with pilonidal disease
    What they received
    various treatments for pilonidal disease, including conservative care, hair removal, injections, and surgery
    Compared with
    different treatment approaches compared with each other (no mention of no treatment or watchful waiting)
    Main outcome
    disease recurrence and treatment-related complications
    Quality
    this is a general narrative review of treatment options, not a study measuring whether cysts resolve on their own, and it says the underlying evidence is low quality.
    Limitations
    abstract states current evidence is limited by study quality with inconsistent definitions and outcome reporting across studies; does not address spontaneous resolution at all.

    Taken word for word from the abstract

    • population The management of pilonidal disease continues to be a challenge due to high rates of recurrence and treatment-associated morbidity.
    • intervention There is a heterogeneous repertoire of treatment modalities used in the management of pilonidal disease and wide practice variation among clinicians.
    • comparator Available treatment options vary considerably in their level of invasiveness, associated morbidity and disability, risks of complications, and effectiveness at preventing disease recurrence.
    • primaryOutcome effectiveness at preventing disease recurrence
    • result the current evidence supporting the different treatment options is limited by study quality with inconsistent characterization of disease severity and use of variable definitions and reporting of treatment-associated outcomes across studies

Included
  • Human, animal or laboratory studies reporting an outcome relevant to the question
Excluded
  • Records about a different condition or intervention
  • Records reporting no outcome
  • Retracted publications, which are listed but excluded from every count
Limits
  • Details were read from abstracts, not full papers, so anything reported only in a paper's methods section is not captured here.
  • Fields were read from abstracts, not full text, so detail reported only in a paper's methods section is not captured.
  • Evidence strength is adapted from the GRADE framework. It is not a GRADE assessment and was not produced by a GRADE panel.

Risks and safetyReported side effects and who should be careful.
  • In one large registry, about half of patients who did not have a procedure at first diagnosis were diagnosed with pilonidal disease again later, suggesting symptoms can return or persist if nothing is done, though this was not compared with a true no-treatment group.
  • Studies that classified disease by severity found that more advanced cysts had higher recurrence after treatment, which suggests delaying care could allow a cyst to become harder to resolve — though this was not directly tested.
Why people try thisThe reasoning behind the question — not a claim that it works.
  • The idea of avoiding surgery, with its pain, scarring, and recovery time, is appealing.
  • Embarrassment about the location can make people delay seeing a doctor and hope it resolves on its own.
  • Mild or intermittent symptoms can make it seem like the problem is already going away.
  • Cost or difficulty accessing surgical care makes a 'wait and see' approach feel like the only option.
Common questionsShort answers, drawn from the same studies.
Do pilonidal cysts go away?
Sometimes symptoms settle down on their own, as seen in one reported case, but there is no good study showing how common this is. Most of the research available looks at treatments, not at cysts left completely alone.
Can a pilonidal cyst go away on its own?
It's possible — one case report describes exactly this happening, twice, in the same person. But with only one documented case, no one can say how often this happens or who it happens to.
Will a pilonidal cyst go away by itself?
There's no reliable evidence to promise this. Some people may see symptoms ease temporarily, as in the one reported case, but it can also come back, and the cyst may still eventually need treatment.
How long does it take for a pilonidal cyst to go away?
No study has measured this. The single case report that describes spontaneous improvement doesn't give a clear timeline, so there's no evidence-based answer to how long it takes.
Should I just wait and not treat it?
The evidence doesn't support confidently waiting it out, since no trial has tested true watchful waiting against treatment. If symptoms worsen, spread, or you develop a painful swelling, that's a sign to see a doctor rather than wait.

This is information, not advice

This page summarises published research. It cannot tell you what is happening in your own body, and evidence changes. If something is bleeding, painful, or new, it is worth being looked at — that is a different question from the one on this page, and a better one to bring to a consultation.
