Thrush (yeast infection)
Yeast infection is a fungal infection caused by Candida albicans. About 1 woman in 5 has Candida in her vagina without it causing any symptoms. Hormones in the vaginal secretions and the “friendly” vaginal bacteria keep it at bay. But problems can arise when this natural balance becomes upset, and the Candida multiplies.
The main symptom of thrush is itching or soreness, and this gets worse in the week before a period. If there is a discharge, it is usually only slight, does not smell and looks like cottage cheese.

Bacterial vaginosis
If your vulva smells fishy sometimes combined with itching, it is almost certain that you have bacterial vaginosis (also known as ‘anaerobic vaginosis’). This is an imbalance in the bacteria in the vagina. All women have harmless bacteria in their vaginal passage. In bacterial vaginosis, some of the bacteria multiply so that more are present than is normal (it is usually the Gardnerella and Mobiluncus bacteria that are the culprits). In other words, bacterial vaginosis is not an infection caught from your partner; it is due to bacteria that are normally present in the vagina.
Trichomoniasis
Trichomoniasis is an infection of the genitals that is caused by the bacterium trichomonas vaginalis (TV). The condition often has no symptoms, but symptoms may include a yellow or green discharge from the vagina with soreness, itching in or near the vagina and discomfort with urination. Infection with Trichomonas vaginalis can be itchy.
Psoriasis
Psoriasis is a skin condition that can be extremely itchy when the genitals are involved. The skin usually becomes bright red, often with painful cracks. The affected area may extend to the groin and to around the back passage (the anus) and between the buttocks. Psoriasis on other parts of the body is scaly (check your scalp, knees and elbows), but in the vulva area it tends to be smooth. You can have psoriasis on the vulva without having it anywhere else on your body.
Lichen sclerosus
is another extremely itchy skin condition affecting the vulva. The itching is often so bad that it can affect a sufferer’s sleep. It is most common around the menopause and in girls just before puberty, though it can occur at any age. Its cause is a mystery. The skin looks thin and pale, and the area around the anus may also be affected. If it is not treated, the lips of the vulva eventually shrink, the vaginal opening narrows and sex becomes painful. Treatment of this condition is simple, and your doctor can prescribe a special steroid cream.
Allergies and sensitivities
Allergy and/or increased sensitivity can cause redness and vaginal itching. The vulva area seems to be very sensitive to chemicals, probably because the vulva is moist and warm – conditions that favour the absorption of chemicals by the skin. It is possible to develop an allergy to almost any chemical substance that comes into contact with the vulva, such as may be present in: skin creams, perfumes in soaps, bubble baths, shower gels and shampoos, disinfectants, washing powders and fabric softeners, deodorants (including ‘intimate’ ones).
Excessive washing
Excessive washing (so called "aggressive hygiene") can irritate the vulva area. Older women who may find it difficult to get into a bath may worry about personal hygiene, with the result that they wash the area too much. There is no need to wash several times a day – once is sufficient. Vaginal douch also should be avoided.
Stress or anxiety
Stress can cause itching. When you are stressed or anxious, your nervous system is on alert, and small sensations can become amplified into unpleasant itching or even pain. So it is not imaginary, it is real.
