What causes vaginal blisters and how should they be managed?

　　Vaginal blistering may be caused by friction irritation, discharge irritation, vulvar eczema, genital herpes, bacterial vaginosis, etc. It can be improved through reducing friction, proper cleaning and care, and medication. If blisters increase, pain worsens, or fever occurs, prompt medical attention is necessary.

　　1. Friction irritation: Wearing tight, non-breathable clothing or frequent sexual activity can cause local friction damage to the vagina, leading to surface blistering accompanied by mild redness and swelling. It is recommended to switch to loose-fitting cotton clothing, avoid excessive friction, and temporarily abstain from sexual activity to allow healing of the local mucosa.

　　2. Discharge irritation: Increased vaginal discharge that is not cleaned promptly can chronically irritate the mucosa, causing inflammatory blistering, often accompanied by vulvar itching and odor. It is advised to wash the vulva daily with warm water, keep the area dry and clean, and change underwear frequently.

　　3. Vulvar eczema: Triggered by allergies or moist environments, vulvar eczema causes red patches and clusters of small blisters on the skin, accompanied by intense itching; scratching may lead to ulceration. It is recommended to use calamine lotion, desonide cream, loratadine tablets, or other medications under a doctor's guidance to relieve symptoms.

　　4. Genital herpes: Caused by infection with the herpes simplex virus, this condition results in clusters of small blisters on the vagina and vulva, accompanied by burning pain and erosion after rupture. Patients may use acyclovir cream, famciclovir capsules, penciclovir cream, or other medications under medical supervision to alleviate discomfort.

　　5. Bacterial vaginosis: Imbalance of vaginal flora leads to overgrowth of anaerobic bacteria, causing inflammation, mucosal congestion, and blistering, along with increased discharge and a fishy odor. Patients may follow medical advice to use metronidazole suppositories, clindamycin cream, tinidazole tablets, or other medications to improve symptoms.

　　Maintain cleanliness and dryness of the vulva, wear breathable cotton underwear and change it regularly, follow a light diet avoiding spicy and irritating foods, engage in moderate exercise to enhance immunity, and minimize local irritants.
