What causes vaginal itching and erosion?

There are many reasons that may cause vulvar itching in female friends. Sometimes, during examination, erosion of varying degrees may be found. This may be related to the lack of attention to private hygiene, resulting in bacterial and viral infections. Sometimes it may be caused by certain gynecological diseases. Below, the editor will introduce some common reasons for vulvar itching and erosion in female friends.

1. Scabies infection: When scabies occurs, the external skin lesions are the most serious, so local itching is also the most obvious.

2. 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.

3. Vaginal 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.

4. 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.

5. 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.

6. Fungal vaginitis: itching of the vulva and vagina, flushing of the vulva, dregs-like leucorrhea with an odor. Scratching may cause eczematous changes of the vulvar dermatitis.

7. Sexual allergy: It is an allergic reaction that occurs during sexual intercourse. There are people who are allergic to semen, condoms, and friction.

8. Viral infection: Genital warts mostly occur in the female vaginal wall, cervical opening and vulva, and also cause foul-smelling leucorrhea. Molluscum contagiosum occurring in the vulva often presents as round papules with an umbilical-like depression in the center, and may also cause itching in the vulva. Genital herpes is often manifested by the appearance of bright, rice-sized blisters on the urethral opening and vaginal wall, in addition to local itching.

Therefore, if you feel vaginal itching for a long time, it is best to go to the hospital in time to find out the cause, and then choose the right medicine for treatment under the guidance of the doctor. During the treatment, you should also pay attention to your diet and try to eat lighter foods. It is best not to eat some hairy and irritating foods.
