HS: information for teenagers

Painful lumps or wounds in places like your armpits, groin, buttocks or under the breasts are uncomfortable — and awkward to bring up.

Hidradenitis suppurativa, usually shortened to HS and also called acne inversa, can begin during the teenage years. This page cannot tell you whether you have it. It can explain what it is and help you decide what to do next.

Could this be HS?

HS often causes recurring painful lumps in skin folds: armpits, groin, buttocks, under the breasts. Some drain fluid, some leave scars, and sometimes tunnels form under the skin.

Other skin conditions look similar. That is why no website can tell you whether you have HS — only someone who examines it can.

Worth mentioning

  • The lump keeps coming back — it heals and then returns.
  • Similar lumps appear in the same kinds of areas — armpits, groin, buttocks or under the breasts.
  • It drains or leaks fluid.
  • It leaves scars or hardened areas behind.
  • More than one body area is affected.
  • Pain affects sitting, walking, sport or school.
  • How long it has been going on — a rough answer is fine.

This is not a checklist and not a test. Nobody is counting how many apply — the list is just here so you don’t forget something that matters at the appointment.

Did I cause this?

Short answer: no. Almost everyone thinks these four things — and all four are wrong.

  • “This is because I don’t wash properly.”

    In fact: No. HS is a chronic inflammatory skin condition. It is not caused by poor hygiene, and washing more often or more vigorously does not prevent it.

  • “I could give it to someone.”

    In fact: No. HS is not contagious. Nobody can catch it from you — not in sport, not in a swimming pool, not from sharing a towel.

  • “If it’s in my groin, it must be something sexual.”

    In fact: No. HS often affects skin folds, and the groin is one of them. Symptoms there do not mean a sexually transmitted infection, and they say nothing about whether someone has had sex.

  • “It’s just spots, I have to put up with it.”

    In fact: Maybe — maybe not. Several skin conditions can look similar, and only a medical examination can tell them apart. Recurring painful lumps are a good reason to raise it rather than wait.

More on this: What is HS?

How do I tell someone?

You don’t have to explain everything at once. Pick a sentence that fits — you can copy it out or send it as a message instead of saying it.

You don’t have to tell anyone just because this page suggests it. Getting to an appointment as a minor usually does need an adult to help, though.

Telling a parent or carer

You don’t have to explain everything at once, and you don’t have to show anyone anything. One sentence is enough to start.

  • “I’ve been getting painful lumps that keep coming back, and I’m worried about them. Can you help me make a doctor’s appointment?”

  • “There’s something happening with my skin that I’m embarrassed about. I can’t explain it properly and I don’t want to show you — but I want a doctor to look at it.”

  • “Can you help me get an appointment without us talking right now about exactly where it is?”

Why it’s worded this way: None of these sentences names a diagnosis. That’s deliberate: you don’t have to know what it is to ask for help.

Telling a doctor

What you say doesn’t have to be complete or sound medical. These sentences are enough.

  • “I’ve had painful lumps in [area] that keep coming back.”

  • “Sometimes it drains / it leaves marks / it makes it hard to sit.”

  • “Could this be HS, or something similar?”

  • “I haven’t shown this to anyone before and I find it difficult.”

Telling someone at school

You do not have to give school a diagnosis. Saying what you need is enough.

  • “I have a health condition that can sometimes cause pain and means I need to deal with a wound. Now and then I may need quick access to a bathroom or a short break. I’d like to discuss it privately.”

  • “I’d rather not talk about this in front of the class. Could we sort it out one to one?”

Why it’s worded this way: If you prefer, you can hand this over in writing instead of saying it — that is what the school support card is for.

Telling friends

You don’t have to tell anyone. Sometimes it’s just easier than inventing reasons.

  • “I have a skin condition that’s sometimes painful. It isn’t contagious.”

  • “I can’t do sport today, it’s a health thing. That’s as much as I want to say about it right now.”

What happens at an appointment?

HS is usually assessed by talking about your symptoms and looking at the affected skin. There is no standard test you have to take beforehand.

You are allowed to say that an area feels embarrassing. You are allowed to ask what will be examined before it starts. And you are allowed to say partway through that it’s too much.

Sentences that help in the room

  • “Can you tell me what you need to examine before we start?”

  • “Can I ask something before the examination?”

  • “Can I have a moment to get changed privately?”

  • “Could the person with me wait outside for part of the conversation?”

  • “I’ve written my questions down — can I give them to you?”

  • “Can we stop for a moment if it gets too uncomfortable?”

  • “Which of the things I say here stays between us?”

What stays private?

The rules about confidentiality depend on age, maturity, the setting and the country, so this page cannot answer that for you in general and does not make you any promises. If it matters to you, ask at the start of the appointment what stays between you — before you share something you’re worried about.

HS at school

School is where HS becomes practical fastest: sitting, changing, PE, the bathroom. For each of these there is something you can ask for.

  • Sitting

    A painful lesion on the buttocks or in the groin can make sitting through a lesson difficult.

    What you can ask for: “Could I stand up briefly or change position when I need to?”

  • Bathroom access

    A dressing change or a draining lesion cannot always wait for the next break.

    What you can ask for: “Could I be allowed to use the bathroom during lessons when I need to manage a health issue?”

  • PE

    During a flare some movements, friction or particular activities can be hard — on other days they are fine.

    What you can ask for: “Could we find an arrangement for the days when things are worse?”

    Important: HS does not automatically mean giving up sport for good. What works right now is something to discuss with your healthcare team — not with a website.

  • Changing rooms

    Changing in front of other people is a completely different thing with visible lesions, scars or dressings.

    What you can ask for: “I have a health condition and would prefer somewhere more private to change. Is that possible?”

  • If something leaks through

    A lesion soaking through clothing is unpleasant — and it is not a hygiene problem and not something to be ashamed of.

    What you can ask for: “Could I keep spare clothing in my locker or at the school office?”

  • Missing school

    If pain, appointments or procedures mean you miss school more often, that becomes a second problem on top of the condition.

    What you can ask for: “How can we make sure I don’t fall behind?”

    Important: If that happens, tell both your healthcare team and someone at school rather than carrying it alone.

You don’t have to say it out loud

If the conversation is hard, you can build a short card and hand it over instead. You choose what goes on it — including whether a diagnosis is named at all. It is created only in your browser.

Friends, swimming and staying over

What you tell people, and what you do, is your call.

You choose who knows

Because HS is not contagious, you never have to tell anyone in order to protect them. It can still be easier to tell one person why you sometimes cancel or sit differently — that’s your decision, not an obligation.

Swimming and sport

HS does not automatically mean giving up swimming or the sports you enjoy. Whether an open or freshly dressed lesion needs something different right now is best checked with your healthcare team.

Sleepovers and staying over

Taking dressing supplies with you and knowing where the bathroom is takes most of the stress out of it. You don’t owe anyone an explanation for going in there.

When people ask

“It’s a skin condition, it isn’t contagious” is a complete answer. You don’t have to show anything or give details.

When it’s getting to you

Pain, scars, drainage and worrying that someone will notice can affect your mood, your confidence, school and friendships. That is common with this condition, and it has nothing to do with how “bad” your skin looks.

If HS is making you avoid school, give up things you normally enjoy, or feel low for a while: tell an adult you trust, or your healthcare team.

Reasons to tell someone

  • You’re avoiding school, or particular lessons, because of your skin.
  • You’ve stopped doing things you normally enjoy.
  • You’ve been feeling low or hopeless for a while.
  • You’re spending a lot of energy hiding it from everyone.
  • It feels like nobody understands what’s going on.

This is not a test and not an assessment. This page cannot judge how you are doing — it is only telling you that talking is worth it.

What if I don’t want to do any of this right now?

That’s fine. “I just wanted to know what this is” is a complete outcome. The page will still be here if you want to come back later.

Evidence and editorial review

Last editorially reviewed: · Next review:

That HS often begins during adolescence, usually after puberty starts, is described in reviews and in patient information from national health bodies. That it is not contagious and not caused by poor hygiene is well established.

That the condition is often recognised late in young people has been described repeatedly. The reported delays differ substantially between studies, because they use different data sources and definitions.

Quality-of-life research in younger patients consists mostly of small cross-sectional studies. They show that substantial burden can occur even when the skin looks relatively unaffected. They do not support any statement about how often that is the case overall.

A higher rate of new-onset depression among young people with HS has been reported in large retrospective cohorts. That says nothing about any individual — which is why these pages run no test and make no assessment.

Treatment recommendations for adults cannot be transferred to adolescents unexamined. The evidence base in younger patients is more limited, which is why these pages name no medicines and give no age-based treatment recommendations.
