What causes blisters on the penis?

Blisters on the penis are often caused by genital herpes, or may be caused by balanitis. Therefore, male friends must pay attention to reproductive health and hygiene in daily life, and pay attention to treatment of any reproductive diseases.

One of the reasons for several small blisters on the penis: genital herpes

Genital herpes is a common sexually transmitted disease, mostly caused by viral infection. Genital herpes usually causes blisters to appear. Genital herpes mostly occurs at the junction of the skin and mucous membranes. First, the local skin becomes slightly red, and then groups of small water scars the size of a needle tip appear, with a mild itchy and burning sensation. After a few days, they dry up and form brown scabs. After the scabs fall off, there is slight pigmentation, but it disappears quickly. The entire course of the disease lasts an average of one week, and it is prone to recurrence.

The second reason for several small blisters on the penis: balanitis

Balanitis is a common infectious disease of the male genitals. Symptoms of balanitis include redness and swelling of the foreskin, burning pain, which worsens during urination, and purulent secretions may flow out of the foreskin. If the foreskin is turned over, it can be seen that the inner layer of the foreskin and the glans penis are congested and swollen. In severe cases, there may be shallow ulcers or erosions, small blisters, and pus.

The third reason for several small blisters on the penis: scrotal eczema

Scrotal eczema is the most common type of eczema, which is limited to the skin of the scrotum, sometimes extending to the area around the anus, and rarely to the penis. The main symptoms of scrotal eczema are diffuse redness, swelling, and severe itching of the scrotal skin. Many pinpoint to rice-sized papules and blisters may appear at the same time. After scratching or rubbing, the erythema, papules, and blisters rupture, revealing large areas of moist erosion, with a large amount of light yellow serous fluid oozing out, some of which condense into pairs of light yellow scabs.
