What are the common causes of vaginal redness, swelling and itching?

Female vulva itching is really embarrassing and uncontrollable. What should you do if this happens when you are at work or your leader is in an important meeting? This really makes many female friends feel very painful and helpless. When I take a shower at night, I find that my vagina is red, swollen and itchy, and my intimacy with my husband decreases. So why does my vagina become red, swollen and itchy?

1. Local skin uncleanness: Some women use toilet paper improperly, and the skin of the vulva is soaked by menstrual blood, vaginal secretions, and even urine, feces and sweat, which causes chronic inflammation of the local skin and causes vulva itching.

2. Trichomoniasis: Itching of the vulva and vagina, foamy leucorrhea, often accompanied by a special odor, and eczematous changes in the vulva after scratching. A vaginal smear test can be used to distinguish it from the above conditions.

3. Drug allergy: "Fixed drug rash" caused by sulfonamides or other drugs in women with allergic constitution often occurs at the junction of the skin and mucous membrane of the vulva. In addition to local itching, it may be complicated by erosion and exudation. Vulvar itching may also occur if allergic reactions and contact dermatitis occur when using drugs for vaginal washing or vaginal insertion.

4. Pubic lice: Pubic lice often stick to the skin surface or attach to the roots of pubic hair. Pubic lice eggs are grayish white and the size of a needle. The bites of pubic lice and their venom and excrement can cause itching and desquamation of the skin, and may lead to eczematous changes and folliculitis.

5. Pinworm infection: It mainly affects young girls, but adult women can also be infected. When the anus relaxes at night, the pinworms crawl out of the rectum and swim to the vulva to mate and lay eggs, and stimulate the skin and mucous membranes of the vulva, causing local itching.

Whether male or female, the skin of the vulva genital area is relatively delicate, and wearing non-breathable underwear in this area for a long time can easily cause eczema. It is also easy to create an environment that is conducive to the growth of pathogenic bacteria and cause bacterial reproduction. Therefore, it is recommended to wear loose pants and cotton underwear instead of silk.
