What are the main manifestations of vulvar itching?

Patient's question:

I have been experiencing itching and redness in my external genital area recently. I wonder if it might be a gynecological disease. I would like to ask what are the symptoms and manifestations of vulvar itching? I want to know how to treat vulvitis. Is there anything that can be done to prevent it?

Doctor's answer:

Treatment of Vulvitis
Vulvitis primarily manifests as itching, pain, or a burning sensation in the external genital area, which worsens during walking, exertion, cycling, or urination. The skin of the external genital area becomes congested, red, and swollen, with increasing amounts of exudate, scratch marks, and sometimes the formation of ulcers. The skin may break open or develop patches of blisters, papules, or eczema. Over time, the skin may thicken, become rough, change in color, and even develop cracks again. Vulvitis is also often accompanied by an increase in vaginal discharge, which may appear yellow and purulent.
Prevention and Care for Vulvitis
Since the onset of vulvitis is primarily related to personal hygiene and cross-infection, it is important to maintain cleanliness to prevent the rampant growth of pathogenic bacteria.
