Itching on both sides of the vulva may be due to the following reasons: first, whether there is vulvar malnutrition, which causes the vulvar skin to become lighter in color and causes itching, and also because of the long history of the disease, which leads to atrophy of the vaginal opening. Second, it may be caused by inflammation, such as Candida vaginitis, trichomonas vaginitis and mycoplasma and chlamydia infections, which may lead to itching on both sides of the vulva. Third, it may be caused by ringworm, which is a rough and flushed skin on both sides of the vulva and inner thighs. No matter what the cause of the itching is, it is recommended to stop eating spicy and sour food and to eat spicy and sour food only after the disease has recovered, and not to drink alcohol and to ensure good sleep.
