What's the reason for the red bump on the glans?

Red bumps on the glans may be caused by balanitis, allergic reactions, genital warts, pearly penile papules, or fixed drug eruptions. It is recommended to seek medical treatment promptly for a clear diagnosis and avoid self-treatment.

1. Balanitis

Balanitis is usually related to bacterial or fungal infection and is common in those with excessive foreskin or poor hygiene. It manifests as glans erythema, itching or white discharge. You can use clotrimazole cream, erythromycin ointment or compound ketoconazole cream 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 contact dermatitis, with red papules accompanied by a burning sensation. Suspicious items need to be stopped immediately, rinsed with water and then apply hydrocortisone cream. People with severe allergies can take oral loratadine tablets or cetirizine tablets.

3. Genital warts

Human papillomavirus infection causes cauliflower-like growths that have a rough surface and bleed easily. After diagnosis, cryotherapy or topical imiquimod cream can be used. It is contagious, so sexual contact needs to be avoided and partners should be notified for joint screening.

4. Pearly penile papules

Benign physiological variations manifest as pearly papules neatly arranged in the coronal sulcus of the glans penis and do not require special treatment. If it affects your life, you can consider laser removal, but there is a possibility of recurrence.

5. Fixed drug eruption

After taking sulfonamides or antipyretic analgesics, a well-circumscribed erythema may appear on the glans, accompanied by itching and pain. After diagnosis, allergenic drugs need to be discontinued, and oral prednisone tablets combined with calamine lotion should be used externally.

You should choose cotton breathable underwear for daily use to avoid local friction and irritation. Use warm water when cleaning and avoid using alkaline soap. During the treatment period, sexual intercourse is prohibited and the changes in the rash are observed. If the red pimple continues to grow, ulcerates, or is accompanied by symptoms such as fever, you must seek immediate medical attention from a dermatologist or urologist. Regular review can help evaluate the effectiveness of treatment and prevent recurrence.
