1. Genital ulcer is a typical symptom of primary syphilis. Ulcers are generally about one centimeter in diameter, and most of them occur in the coronal groove of penis in men, and most of them occur in labia majora, labia minora or cervix in women. Because there is no obvious pus on the surface of the ulcer, the patient himself does not feel pain and is often ignored until the secondary syphilis rash appears.
2, vulva warts may be infected with condyloma acuminatum. Patients infected with condyloma acuminatum generally do not feel uncomfortable, neither causing pain and discomfort in urination, nor causing vulvar ulcers. It happened quietly and gradually increased until one day, the patient noticed a small wart in the vulva intentionally or unintentionally. Condyloma acuminatum is more common in men than in women, such as coronary sulcus, penis and inside of foreskin, but it can also occur in other parts of the urogenital system, such as urethral orifice and cervix.
3, the small blisters that appear in the vulva may be infected with genital herpes. It is characterized by a small pile of about 4 ~ 5 small blisters in the vulva, with burning or tingling sensation locally. These small blisters soon burst into small pieces of rotten noodles. Genital herpes is usually mild. Even if it is not treated, it can grow up in about 7 ~ 10 days, but it is easy to recur, which brings great psychological pressure to patients.
4. There is purulent secretion at the urethral orifice, and gonorrhea should be suspected.
