Patient's question:
A blister has grown on the penis, oxygen. It broke a few days ago and has grown back.Doctor's answer:
Hello, small blisters in the vulvar area may be caused by conditions such as genital herpes, miliaria, or other lesions. Miliaria is an acute inflammatory and itchy skin disease caused by blocked sweat ducts and retained sweat. The typical lesions are small, transparent, and taut vesicles without inflammation. Genital herpes is caused by infection with the herpes simplex virus, with an incubation period of 2-7 days. It presents with erythema, itching, clustered small vesicles in the genital area, thin-walled vesicles that rupture and form erosion, leading to small pustules with a burning sensation, and sometimes ulcers. Other irritants such as allergies can also trigger it. Therefore, it is recommended that you visit a hospital for relevant examinations to confirm the diagnosis.
