There is a particular pattern that brings people back to a clinic three and four times: itching, a course of antifungal treatment, two good weeks, and then the same itching again. At some point it stops being a stubborn infection and starts being a sign that the diagnosis was never quite right — because the vulva is skin, and skin gets the conditions that skin gets.
Inside and outside are different problems
The vagina is the canal on the inside. The vulva is everything on the outside — the labia, the clitoral hood, the skin around the opening. They sit next to each other and get spoken about as one thing, but they are made of different tissue and they go wrong in different ways.
Vaginal problems tend to produce discharge. Thrush, bacterial vaginosis and trichomonas all change what comes out, and treating the infection resolves the itch along with it. Vaginal infections covers those.
Vulvar problems tend to produce itching, soreness and changes you can see, with normal discharge or none at all. These are skin conditions, and antifungal cream does very little for them — which is precisely why they turn into a cycle of treatment that nearly works.
What is usually behind it
| Cause | What tends to point at it |
|---|---|
| Contact irritation | Itching that started after a new pad, wash, wipe, detergent or hair removal, and that flares with use. |
| Eczema or psoriasis | Dry, flaky or thickened patches; often a history of the same thing elsewhere on the body. |
| Low oestrogen | After menopause, while breastfeeding, or on some contraception — thin, dry, easily sore skin, often with discomfort during sex. |
| Lichen sclerosus | Pale, white, crinkled or shiny skin, intense itching especially at night, and slow change to the shape of the labia. |
| Thrush, genuinely | Real, and worth confirming rather than assuming — but it should resolve with treatment and stay resolved. |
The first of those is the one most often missed, because the products involved are marketed as hygiene and nobody suspects them. Intimate washes, scented pads and liners, wet wipes, fabric softener, and the days after shaving or waxing are all common triggers — and the more irritated the skin becomes, the more people wash, which is the loop that keeps it going.
Low oestrogen deserves a mention of its own because it is so often filed under ageing and left there. It is treatable, usually with something applied locally, and menopause care and pain and dryness both go into it further.
The one not to leave alone
Lichen sclerosus is a long-term skin condition that affects the vulva in particular. It is not an infection, it is not caught from anyone, and it is not anyone's fault. It is also, among everything on the list above, the one that does something if ignored.
- Skin that looks pale or white, sometimes crinkled like tissue paper, sometimes shiny and tight.
- Itching that is worse at night and can be severe enough to wake you.
- Small splits or tears in the skin, often with sex or wiping.
- Gradual change to the shape of the area — the inner labia flattening, the clitoral hood sealing over, the opening narrowing.
That last point is the reason this one matters, and it is the part that treatment prevents rather than reverses. The changes come on so slowly that they are often put down to age and only noticed in hindsight.
People are often nervous about strong steroids, which is reasonable in general and misplaced here: the course is prescribed for this skin, in this place, with a defined plan and review. Under-treating is the far more common problem, and it is the one with a cost.
What the visit involves
Most of this diagnosis is made by looking, which is quick and is the part people most dread. It helps to know that the examination is brief, that you can ask for it to stop at any point, and that nothing about the appearance of this area is remarkable to someone who looks at it all day.
- A conversation about where it itches, when it started, what is worse at night, what you have already tried and what the products are.
- Looking at the skin, which is where the diagnosis usually comes from.
- Swabs to rule infection in or out, so that antifungal treatment stops being a guess.
- A small biopsy, sometimes — done with local anaesthetic, taking minutes, when the appearance is not clear or treatment has not worked as expected.
If you have been treated for thrush more than twice without it holding, say so in those words. It changes the direction of the visit immediately, and it is the single most useful sentence you can bring.
The part that is about stopping things
Whatever the diagnosis turns out to be, the same everyday changes help, and for contact irritation they are the entire treatment rather than an accompaniment to it.
- Stop the intimate washes. The vulva does not need cleaning products, and most of them are mild irritants used daily on skin that is already sore.
- Water only on the outside, or a plain unscented emollient used as a soap substitute if something is wanted.
- Stop the wet wipes, including the ones sold as gentle — they are a common cause rather than a remedy.
- Unscented pads, and cotton underwear that is not tight. Nothing overnight that does not need to be there.
- Pause hair removal in the area while the skin settles.
- Skip fabric softener on underwear.
One more thing, and it matters: itching leads to scratching, and scratching keeps the skin inflamed long after the original cause has gone. Breaking that loop — often with something prescribed to settle the itch quickly — is frequently what finally ends a cycle that has been running for months.
Common questions
I have taken thrush treatment several times. Why does it keep coming back?
Either it is thrush and something is feeding it, or — more often at this point — it was never thrush. Treatment that nearly works and then fails is the classic pattern for a skin condition on the vulva rather than an infection in the vagina. After two courses that did not hold, the useful next step is having the skin looked at and a swab taken rather than a third course.
Should I be using an intimate wash?
No, and if your skin is irritated it is one of the first things to stop. The vagina cleans itself and the vulva needs nothing more than water. These products are among the most common causes of the itching they are bought to relieve, which is an unfortunate loop to be caught in.
Is lichen sclerosus cancer?
No. It is a long-term skin condition, not a cancer and not a pre-cancer in itself. Left unmanaged over many years it carries a small increase in the risk of vulvar cancer, and treating it is what removes most of that — which is the reason to confirm it and treat it rather than live with the itching.
Is it safe to use a strong steroid there for a long time?
Used as prescribed for this condition, yes — the regimen is designed for this skin, tapers once things settle, and is reviewed at intervals. The far more common problem is using too little out of worry, which leaves the condition active and allows the changes it causes to continue. Raise the concern at the visit rather than solving it by using less.
Is itching after menopause the same thing?
Often it is low oestrogen rather than any of the above — thinner, drier skin that is more easily irritated. It responds well to treatment applied locally. But lichen sclerosus is also more common around and after menopause, so persistent itching at that age is worth having looked at rather than assuming it is simply the change.
