Speaking to the NHS, Dr Suzy Elneil, a consultant in urogynaecology and uro-neurology at University College Hospital, London, claims that itching can be a sign of thrush or other infection, but it can also have other causes.
"Itching can be part of a generalised skin problem, such as eczema," she says. "Or it can be a sign of benign or malignant (cancerous) changes to the skin, such as lichen sclerosus or vaginal intra-epithelial neoplasia.
"All need treatment, so if the itch persists for more than a month, get it checked by a GP or gynaecologist. They need to see the vulva, perineum (between the vagina and anus) and the vagina directly."
Vaginal thrush is one of the most common causes of itching or irritation in the genital area. This is a yeast infection that occurs when candida grows excessively in the vagina and vulva, and the NHS estimate it will affect three out of every four women at some point in their lives.
