Red spots and small bumps like pimples have appeared on the glans.

Small red bumps or pimple-like spots on the glans are usually caused by friction, allergic reactions, eczema, pearly penile papules, balanitis, or other factors. Treatment should be based on the specific cause. Detailed analysis is as follows:

1. Friction

Poor-quality underwear can cause prolonged friction with the foreskin, leading to the aforementioned symptoms. It is recommended that patients choose well-made, loose-fitting, and comfortable underwear, and change and wash them regularly.

2. Allergic Reaction

In some individuals, small bumps on the glans may result from an allergic reaction to hygiene products, partner's secretions, or other substances. Allergic reactions may cause redness, swelling, and small bumps. Under medical guidance, antihistamines such as cetirizine hydrochloride tablets or loratadine tablets may be used for treatment.

3. Eczema

Eczema is a type of skin inflammation that may cause small bumps and red patches on the glans. It can be triggered by allergies, dryness, humidity, irritants, or other factors. Symptoms may be relieved using medications such as calamine lotion or prednisone acetate cream, as directed by a physician.

4. Pearly Penile Papules

This skin condition, often caused by long foreskin and local irritation, may lead to the appearance of red or white papules around the glans or coronal sulcus. Treatments such as adapalene gel or metronidazole gel may be used under medical supervision.

5. Balanitis

Balanitis is typically an inflammatory condition caused by infection, trauma, or irritation, resulting in swelling, bleeding, and pain in the foreskin and glans. Treatment may include topical application of compound Phellodendron liquid or oral administration of levofloxacin hydrochloride capsules, under a doctor’s guidance.

If symptoms persist or worsen, prompt medical attention is advised. Avoid scratching with hands and maintain cleanliness of the affected area.
