Why Am I Itchy Down There? Causes and What Settles It

Itch down there has about eight common causes, and the pattern points to the likely one: itch with a thick white discharge is usually thrush; itch with a fishy smell is more often bacterial vaginosis (BV), though BV does not usually itch; and itch with no discharge is more often skin than infection, from washing products, shaving, a cream, dryness or lichen sclerosus.^{1, 2, 3} Tonight, water, an unperfumed emollient and nothing scented settle most of them; what fixes it is what a swab decides. Part of the Wellgard BV guide.

Why am I itchy down there, and what does the pattern point to?

The itch itself does not sort the causes: in a survey of 2,888 women, itching was reported by 12% with BV and 15% without, and of 95 women buying a thrush treatment for self-diagnosed thrush, 33.7% had thrush, 18.9% BV and 13.7% nothing.^{4, 5} The NHS says "do not self diagnose"; the table chooses the route, not the diagnosis.⁶

Is it thrush?

The NHS lists a white discharge, often like cottage cheese, that does not usually smell; itching and irritation; and soreness or stinging during sex or when you pee.¹ Discharge is optional: in 774 clinic women the signs included redness, swelling and skin splits.⁷ Antibiotics are the clearest trigger: in a small US study, 6 of 27 women on a short course developed thrush against none of 27 comparison women.⁸ Recurrent thrush means four or more episodes a year, and NICE's summary says thrush "is frequently over-diagnosed".⁹ Vaginal thrush, what causes thrush and is thrush contagious cover treatment, triggers and partners.

Could it be BV, trichomoniasis or a UTI instead?

The NHS says BV "does not usually cause any soreness or itching"; its signature is a thin grey discharge with a fishy smell, and its treatment is an antibiotic, as how BV is treated sets out.² Trichomoniasis, an STI, does itch: the NHS lists itching, soreness, swelling or redness with a frothy yellow-green discharge, notes that "many people get no symptoms at all", and partners need treatment too.¹⁰ A urinary tract infection is a different organ: burning on passing urine, urgency and frequency, no skin itch, a urine sample and an antibiotic from a pharmacist or GP; thrush stinging as urine crosses sore skin is easily read as cystitis. Is it thrush, BV or something else puts nine causes in one table; what your discharge means reads the discharge.

Why am I itchy with no discharge?

Because the skin, not the vagina, is usually the problem: in a specialist series of 144 women with long-standing vulval symptoms, 64% had dermatitis and 7% lichen sclerosus; psoriasis, vulvodynia and chronic thrush shared the remaining 15%.³

Irritation and allergy. Of 282 UK women patch-tested for vulval symptoms, 54% had allergic contact dermatitis, most relevantly to fragrances and to antibiotic or anaesthetic creams.¹¹ Irritant dermatitis is commoner still: washes, wipes, liners, detergent, spermicide, the thrush cream.¹²

Lichen sclerosus. The NHS describes itchy white patches, smooth or crinkled, that bleed if scratched, "much more common in women over 50", not an infection, not contagious and "not caused by poor personal hygiene".¹³ The treatment is prescription-only: in a Cochrane review of seven trials, a potent steroid ointment improved symptoms against placebo (risk ratio 2.85).¹⁴ It raises the risk of vulval cancer, though "the risk is low", so it is followed up long term and a lump, thickening or ulcer that does not go away is reported.¹³

Dryness, at any age. Itching is on the NHS list of dryness symptoms, with the menopause, breastfeeding, hormonal contraception, some antidepressants and perfumed washes among the causes.¹⁵ Vaginal atrophy and soreness after the menopause explains "thrush" that swabs negative; vaginal dryness covers every age.

How do I stop the itching tonight?

With the NHS self-care list, the same on its thrush, lichen sclerosus and itchy-skin pages: water and an unperfumed emollient as a soap substitute, dab dry, a cool damp towel, "pat or tap your skin instead of scratching it", loose cotton, petroleum jelly as a barrier on split skin, short nails.^{1, 13, 16, 17} Stop everything scented: soaps, shower gels, bubble bath, deodorants, wipes, douches, liners and fragranced washing powder.^{13, 16} Burning gets the same first move.

Not: an antifungal "just in case" (two thirds of self-diagnosed thrush is something else, and the cream can become the allergen), a steroid without a diagnosis, home remedies inserted, hot baths.^{5, 11, 6} Emollients on fabric catch fire more easily.¹³ None of this fixes an infection or a skin disease; it takes the edge off while the swab decides.

Which cream is right: antifungal, steroid or emollient?

Three creams, three jobs. An antifungal is the treatment for thrush; the NHS says a pharmacist can sell one if thrush has been diagnosed before, and not more than twice in six months without asking a pharmacist or doctor.¹ A steroid is for a diagnosed skin condition such as lichen sclerosus or dermatitis, on prescription, at the strength and for the time the GP sets.^{13, 16} An emollient is for everything else and alongside both: nothing in it to react to, and first on the NHS list.^{1, 13}

Why does it itch before my period, after sex or after shaving?

Before a period. In the 774-woman series a positive candida culture went with presenting after day 14 of the cycle, so a monthly pre-period itch fits thrush; the NHS says a GP can help identify triggers "such as your period or sex".^{7, 1}

After sex. Friction on dry skin, latex or spermicide and, rarely, semen: in a 14-year series of 92 women, three reacted to latex and two to seminal plasma.¹² Sex also triggers thrush and passes on trichomoniasis, so itch after a new partner is a clinic visit, and the NHS says "do not have sex until you've seen a doctor or nurse".^{1, 10, 6} Try a water-based lubricant and a non-latex condom.

After shaving or waxing. No study has measured it; the NHS says thrush develops more easily when "your skin is irritated or damaged", and that rubbing or damage can trigger lichen sclerosus.^{1, 13} Emollient, no more shaving until it settles, and a GP if spots spread or fill with pus.

When should I see a GP or a sexual health clinic?

For any white patch, skin change, bleeding, sore or ulcer; an itch that does not get better with self-care or keeps coming back; thrush symptoms for the first time, under 16 or over 60, more than four times in 12 months, or after a treatment has not worked; pregnancy or breastfeeding (itchy skin in pregnancy is a GP or midwife matter, the NHS says, as it can sometimes be a liver condition); diabetes or a weakened immune system; a new partner; fever, chills or pelvic pain; and any bleeding after the menopause, between periods or after sex.^{1, 13, 17, 6, 15} Sexual health clinics need no referral.⁶ Boric acid pessaries and irritation covers burning after a pessary.

Frequently asked questions

How do I stop itching down there immediately?

Cool water, a damp cool towel, an unperfumed emollient and loose cotton, nothing scented, no scratching.^{1, 17} That settles most skin irritation within an hour or two; it cannot fix thrush, BV, trichomoniasis or lichen sclerosus, so an itch that is back the next night needs a swab.

Can live cultures help with itching?

No trial has measured itch as its main outcome. In the Cochrane review of ten trials (1,656 women), live cultures added to antifungal treatment gave a small short-term gain in symptom resolution (risk ratio 1.14) and fewer relapses at one month (risk ratio 0.34, very low quality), with no benefit at three months; the antifungal remains the treatment.¹⁸ The live-culture evidence for the vagina has the detail.

Why am I itchy but the swab was clear?

A clear swab makes thrush, BV and trichomoniasis unlikely and points at the skin: dermatitis from a product or cream, lichen sclerosus, dryness, eczema or psoriasis, or nothing visible, where vulvodynia sits.^{3, 11, 13, 19} Ask for the skin to be examined, use water and emollient only, and ask for a referral if it persists, which NICE lists as a reason.¹⁶

What does vulval inflammation look like?

In words: redness and swelling of the outer lips, small splits in the skin folds, thickened skin where scratched and, with lichen sclerosus, white smooth or crinkled patches that bleed easily.^{7, 13} A lump, thickening or ulcer that does not go away is a GP visit.¹³
