Small blisters on the skin of the penis may be caused by genital herpes virus infection, cysts, burns or crush injuries.
1. Herpes virus infection: genital herpes virus infection is a common cause of blisters, and most patients have a history of unclean sexual contact. The location of the blisters is itchy and tingling, and ulcers are formed when they break down. It is necessary to actively use antiviral drugs for treatment, such as acyclovir.
2. Cysts: cysts can also lead to the appearance of small blisters, the surface is relatively smooth, usually no pain, can grow on the surface of the penile skin, urethral orifice, tethered belt and other locations. Surgery is needed to remove them if necessary.

Overall, men with long blisters on the penile skin need to pay attention, go to the hospital in time for examination, and carry out targeted treatment after clarifying the cause of the disease.
