Frequently asked questions
I keep treating thrush but the itching returns. Why?
Because it is often not thrush. Persistent vulval itching that does not respond to antifungal treatment is more likely to be lichen sclerosus, eczema, contact dermatitis from washes and wipes, or vulval atrophy after the menopause. Each needs different treatment.
What is lichen sclerosus?
A chronic inflammatory skin condition of the vulva causing itching, whitening and thinning of the skin. Over time it can change the vulval architecture. It is common, frequently missed for years, and responds well to a potent topical steroid used correctly.
Are strong steroid creams safe to use there?
Used as directed, yes, and undertreating is the more common problem. Lichen sclerosus needs a potent steroid, applied in a specific way and then reduced to a maintenance regimen. Fear of steroids leads to years of unnecessary symptoms.
Will I need a biopsy?
Not usually. The diagnosis is generally made on appearance. A biopsy is arranged where the appearance is atypical, where treatment does not work as expected, or where there is any area of concern that needs to be identified rather than assumed.
Is lichen sclerosus linked to cancer?
There is a small long-term increase in the risk of vulval cancer, which is why the condition is monitored rather than treated once and forgotten. Well-controlled lichen sclerosus with periodic review is the aim, and treatment appears to reduce that risk.
What should I stop using?
Soaps, shower gels, feminine washes, wipes and douches, all of which commonly worsen vulval skin conditions. Plain emollient as a soap substitute is usually better. Bring whatever you have been using, as the cause is sometimes in the bag.
