What to do if blisters appear on foreskin?

The so-called foreskin refers to the outer skin of the male penis. For Chinese men, it is very common to have an excessively long foreskin. Although it sometimes does not affect sexual ability and fertility, it is easy for the foreskin to accumulate dirt, which may result in inflammation of the glans penis. Therefore, it is also necessary for men to frequently clean the dirt inside the foreskin. So, what should I do if the foreskin has blisters?

Genital herpes is a sexually transmitted disease caused by the herpes simplex virus (HSV), mainly HSV-2, and a small number of HSV-1. It is one of the most common sexually transmitted diseases. Genital herpes can recur, which has a great impact on the patient's health and psychology; it can also infect newborns through the placenta and birth canal, causing congenital infection in newborns. Therefore, this disease is also one of the more serious public health issues, and its effective prevention and treatment should be taken seriously.

Causes

HSV-2 is the main pathogen of genital herpes (90%), which causes primary genital herpes after infection. After the initial genital herpes subsides, the remaining virus transfers along the nerve axis through the peripheral nerves to the sacral ganglia and remains dormant for a long time. When the body's resistance is reduced or certain stimulating factors such as fever, cold, infection, menstruation, gastrointestinal dysfunction, trauma, etc., the latent virus can be activated and the virus will move down to the surface of the skin and mucous membranes to cause damage and lead to recurrence. Humans are the only host of herpes virus. The virus cannot survive outside the human body. Ultraviolet rays, ether and general disinfectants can inactivate it.

Clinical manifestations

1. Initial onset of genital herpes

Initial genital herpes can be divided into primary genital herpes and non-primary initial genital herpes. The former is the first time that symptoms appear after infection with HSV, which is primary genital herpes. Its condition is relatively serious. Some patients have had HSV-1 infection in the past (mainly oral or facial herpes) and then were infected with HSV-2 again, which is the first onset of genital herpes. This is non-primary initial genital herpes, and its condition is relatively mild.

(1) The incubation period is 3 to 14 days.

(2) There are clusters or scattered small blisters around the external genitalia or anus, which rupture to form erosions or ulcers after 2 to 4 days and cause spontaneous pain.

(3) Inguinal lymph nodes are often enlarged and tender.

(4) Patients may experience systemic symptoms such as fever, headache, and fatigue.

(5) The course of disease is 2 to 3 weeks.

2. Recurrent genital herpes

After the primary skin lesions subside, the rash recurs. Recurrent genital herpes is milder than primary systemic symptoms and skin lesions and has a shorter course.

(1) There is a local burning sensation, tingling sensation or abnormal sensation before the rash appears.

(2) Clusters of small blisters appear around the external genitalia or anus, which quickly rupture to form erosions or shallow ulcers. The symptoms are perceived to be mild.

(3) The course of disease is 7 to 10 days.
