    Blisters on the glans may be related to factors such as genital herpes, contact dermatitis, balanitis, fixed drug eruption or friction injury. Blisters usually appear as partially transparent or turbid vesicles, which may be accompanied by itching, pain or exudation, and require targeted treatment based on the specific cause.

    1. Genital herpes

    It is caused by infection with herpes simplex virus type 2 and is mainly spread through sexual contact. The blisters are distributed in clusters and form shallow ulcers after ulceration, which may be accompanied by inguinal lymph node enlargement. It is necessary to use acyclovir cream, famciclovir tablets or penciclovir gel for antiviral treatment as directed by your doctor, and avoid sexual contact to prevent infection.

    2. Contact dermatitis

    Caused by exposure to allergens such as condom materials, detergents or topical medications. The skin around the blisters is obviously red and swollen, accompanied by severe itching. Topical mometasone furoate cream or oral loratadine tablets can be used to relieve symptoms. In severe cases, desonide cream is required. Daily checks should be made to avoid contact with allergenic substances.

    3. Balanitis

    It is mostly caused by bacterial or fungal infection and is common in people with excessive foreskin. The blisters are accompanied by white discharge, redness and swelling of the glans, and burning pain during urination. Clotrimazole cream needs to be used to treat fungal infections, and mupirocin ointment can be used for bacterial infections. Circumcision is recommended for recurrent attacks.

    4. Fixed drug eruption

    Allergic reactions caused by specific drugs such as sulfonamides and antipyretics and analgesics. The borders of the blisters are clear and pigmentation remains after healing. Allergenic drugs need to be stopped immediately, and oral ebastine tablets combined with halomethasone cream should be used externally. You need to clearly inform your doctor about your allergy history before taking any medication in the future.

    5. Friction damage

    Mechanical damage caused by friction from clothing, excessive cleaning, or sexual activity. The blisters are small and isolated, and may bleed slightly on the surface. Keep the affected area dry and clean, avoid squeezing, and apply erythromycin ointment to prevent infection. Choose loose-fitting cotton underwear to reduce friction and irritation.

    If glans blisters occur, avoid scratching or opening them yourself. Wash them with warm water every day and keep them dry. Suspend sexual intercourse until recovery, and observe whether it is accompanied by systemic symptoms such as fever and swollen lymph nodes. If the blisters do not subside within 3-5 days, expand in area, or become suppurative, you need to go to a dermatology or urology department in time. If necessary, perform herpes virus testing, secretion culture and other examinations to clarify the cause. Paying attention to perineal hygiene on a daily basis, avoiding the use of irritating lotions, and controlling blood sugar can reduce the risk of infection.
