Why is there a red spot on my foreskin?

Redness in a patch of foreskin may be related to local irritation, allergic reaction, infection and other factors, and usually manifests as redness, swelling, itching, pain and other symptoms. It can be relieved by keeping clean, topical medications, oral medications, etc.

1. Local stimulation

Redness of the foreskin may be caused by local friction or chemical exposure. Wearing tight clothing for long periods of time and using harsh bath products may cause damage to the skin barrier. It is recommended to change to loose-fitting cotton underwear, avoid using fragrance-containing detergents, wash gently with warm water every day and keep dry. If there is slight desquamation, you can use zinc oxide ointment to protect the wound as directed by your doctor.

2. Allergic reaction

Contact allergens such as condom materials and detergent residues may cause allergic dermatitis. Typical symptoms include well-circumscribed erythematous lesions with severe itching that may include small papules or vesicles. Suspected allergens need to be stopped immediately and cold compresses can be used to relieve discomfort. If necessary, hydrocortisone butyrate cream should be applied for a short period of time under the guidance of a doctor, combined with oral loratadine tablets for anti-allergic treatment.

3. Bacterial infection

Invasion of pathogenic bacteria such as Staphylococcus aureus may cause folliculitis or superficial skin infection, which manifests as local redness, swelling, heat and pain. In severe cases, purulent secretions may be seen. It is necessary to seek medical treatment for secretion testing. After diagnosis, external mupirocin ointment can be used for antibacterial treatment. When combined with fever, cefaclor dispersible tablets should be taken orally. Daily disinfection of the perineum needs to be strengthened to avoid scratching which may lead to the spread of infection.

4. Fungal infection

Candida infection is common in people with diabetes or long-term antibiotic use. It is characterized by erythema with raised edges and white filmy secretions, and satellite lesions can be seen around it. Diagnosis requires skin scraping and microscopic examination. The first choice for treatment is local application of clotrimazole cream. In stubborn cases, fluconazole capsules must be taken in combination. Keep the affected area ventilated and dry, and avoid sexual intercourse during treatment.

5. Balanitis

People with excessive foreskin are prone to non-specific balanitis, which manifests as diffuse congestion with burning sensation, and may be accompanied by urethral discharge. Mild inflammation can be diluted with potassium permanganate solution for sitz bath. In the acute stage, compound ketoconazole cream should be used under the guidance of a doctor to control inflammation. Those with recurrent attacks should consider circumcision and use red light physiotherapy to promote healing after surgery.

Daily care should be taken to wash the inside and outside of the foreskin with warm water every day and avoid using alkaline soap. Choose pure cotton breathable underwear and change it daily, and clean it before and after sex. It is advisable to consume more B vitamins and zinc in your diet, such as lean meat, whole grains, etc. to help skin repair. If symptoms of persistent redness, swelling, ulceration or fever occur, you must see a urologist promptly. It is forbidden to use strong hormone ointments on your own. Suspend strenuous exercise during treatment to prevent friction from aggravating inflammation.
