What is the reason for the red spots on the glans and itching?

Red spots and itching on the glans may be related to balanitis, allergic reactions, fungal infections, contact dermatitis, trichomonas infection and other factors. This symptom is usually caused by local irritation, pathogen infection or immune abnormality, manifesting as erythema, papules or exudation, and requires targeted treatment based on the specific cause.

1. Balanitis

Balanitis is mostly caused by bacterial or candida infection and is common in people with excessive foreskin. Symptoms include redness, swelling, burning sensation, and white discharge from the glans penis. You can use clotrimazole cream as an antifungal or erythromycin ointment to control bacterial infections as directed by your doctor. Keep the area clean and dry daily and avoid scratching.

2. Allergic reaction

Contact with allergenic substances such as condoms and detergents may cause allergic dermatitis, which manifests as dense red rash with severe itching. Suspicious items need to be stopped immediately, rinse with water and apply hydrocortisone cream externally to relieve symptoms. The author recommends allergen testing for recurrent relapses.

3. Fungal infection

Candida albicans infection is common in people with diabetes or long-term antibiotic use. It is characterized by red patches with clear edges and surrounding satellite lesions. Miconazole nitrate powder can be sprayed locally and taken orally with fluconazole capsules. Partners need to be treated simultaneously to prevent cross-infection.

4. Contact dermatitis

Chemical irritation, such as dye residue in new underwear, can cause contact dermatitis, with well-defined erythema and blisters. Use cold compresses with normal saline initially, and then apply zinc oxide ointment to protect the wound after the leakage is reduced. Avoid wearing underwear made of chemical fiber.

5. Trichomonas infection

Trichomonal urethritis can be transmitted through sexual contact. In addition to the red spot on the glans, it is often accompanied by itching and foamy discharge from the urethra. Diagnosis requires microscopic examination, treatment with oral metronidazole tablets, and sexual partners must take the drug at the same time. Sexual intercourse is prohibited during treatment.

If you have the above symptoms, you should avoid self-medication and seek medical advice promptly to find out the cause. Pay attention to the ventilation of the perineum every day, choose pure cotton underwear and change it every day. Avoid spicy food in your diet, and those with allergies should record suspected allergens. If the red spots continue to increase or symptoms such as ulceration and fever appear, seek medical attention immediately to rule out sexually transmitted diseases or other serious infections.
