What's wrong with the blisters on the foreskin?

Blisters on the foreskin may be related to factors such as genital herpes, contact dermatitis, balanitis, allergic reactions, friction injuries, etc., which can be improved through antiviral treatment, topical medication, anti-allergic treatment, and keeping clean. It is recommended to seek medical treatment promptly for a clear diagnosis and avoid self-treatment.

1. Genital herpes

Genital herpes is caused by herpes simplex virus type 2 infection and is mainly spread through sexual contact. The blisters are distributed in clusters, accompanied by burning or itching, and ulcers form after rupture. Antiviral drugs such as acyclovir cream, famciclovir tablets, and penciclovir gel must be used as directed by your doctor. Sexual intercourse should be avoided during the onset of the disease to prevent infecting others.

2. Contact dermatitis

Contact with irritating substances such as condoms and detergents may cause local allergic reactions, manifested as erythema, blisters and severe itching. Topical hydrocortisone cream and calamine lotion can be used to relieve symptoms. In severe cases, loratadine tablets can be taken orally. It is necessary to avoid contact with allergenic substances in daily life and choose additive-free cleaning products.

3. Balanitis

Inflammatory reactions caused by fungal or bacterial infections are common in people with excessive foreskin. When Candida albicans is infected, white discharge and dense blisters appear, which need to be treated with clotrimazole cream and miconazole nitrate powder. Mupirocin ointment can be applied for bacterial infection, and circumcision should be considered for patients with phimosis.

4. Allergic reaction

Localized blistering rash may occur when you are allergic to underwear materials, condom lubricants and other substances. Oral cetirizine drops can be taken to relieve symptoms, and local cold compresses can be used to reduce swelling. It is recommended to change to pure cotton underwear, avoid using fragrance-containing hygiene products, and conduct allergen testing if necessary.

5. Mechanical friction

Intense sexual intercourse or friction with clothing may cause epidermal damage and the formation of clear tension blisters. Keep the affected area dry and clean, and avoid scratching. It usually heals on its own in 3-5 days. If symptoms occur repeatedly, you need to check whether there is a problem of excessive foreskin. It is advisable to choose loose and breathable underwear every day to reduce friction.

If foreskin blisters occur, the perineum should be washed with warm water every day and avoid using irritating soaps. No sexual intercourse during treatment, and observe whether the blisters expand or suppurate. The diet should be light and the intake of spicy food should be limited. If it is accompanied by symptoms such as fever and swollen inguinal lymph nodes, you should seek medical attention immediately to check for serious infection. After patients with circumcision are cured, it is recommended to evaluate whether surgical treatment is needed to prevent recurrence.
