What are the causes of vulvar and perianal itching?

If you have itching around the vulva and anus, you must pay attention to the causes. Common causes include fungal and Trichomonas vaginitis, which can cause itching around the vulva and anus. Allergies caused by the use of some drugs can also cause itching symptoms.

Trichomonas vaginitis is the most common cause of vulvar itching. Lice and scabies can also cause itching. The itching around the anus and vulva of young girls caused by enterobiasis usually only occurs at night.

It should be noted that when cleaning the vulva every day, it is more appropriate to use a female care solution with a weak acid formula of Ph4.
