10 major dirty hands that can easily cause "private itching"

Vulvar pruritus refers to the symptoms of vulvar pruritus caused by different vulvar diseases. However, it can also occur in people with normal vulva appearance. When the itching is severe, the person will be restless and it will seriously affect their work and study. Although the prognosis of vulvar itching is good, the disease itself brings more pain to the patient. Therefore, it is important to develop good hygiene habits in daily life. In fact, vulvar itching is a very common symptom, and many gynecological diseases will have symptoms of vulvar itching.

1. Trichomoniasis

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

2. Fungal vaginitis

Itching of the vulva and vagina, flushing of the vulva, and leucorrhea resembling bean curd residue with an odor. Scratching may cause eczematous changes of the vulva dermatitis.

3. Local skin is unclean

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.

4. 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.

5. Genital skin diseases

The skin lesions of tinea cruris often extend to the vulva, causing severe local itching. The local itching caused by vulvar eczema and neurodermatitis is more severe. The former is manifested as papules and blisters with unclear local skin boundaries and erosion exudate, while the latter often causes thickening of the skin with lichenification due to scratching. In addition to causing local itching, leukoplakia of the vulva is often accompanied by vulvar malnutrition and skin atrophy.

6. Viral infection

Genital warts mostly occur on the female vaginal wall, cervix and vulva, and may 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, accompanied by local itching.

7. Sexual allergy

This is an allergic reaction that occurs during sexual intercourse. There are people who are allergic to semen, condoms, and friction.

8. Pinworm infection

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

9. Pubic lice

Pubic lice often lie on the surface of the skin or attach to the roots of pubic hair. Pubic lice eggs are grayish white and the size of a pinhead. 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.

10. Scabies infection

When scabies occurs, the external skin lesions are the most severe, so local itching is also the most obvious.
