What causes red spots and itching on the glans?

Itchy red spots on the glans may be related to factors such as balanitis, allergic reactions, fungal infections, contact dermatitis, and trichomonas infection. It is recommended to seek medical treatment promptly for a clear diagnosis and carry out targeted treatment under the guidance of a doctor.

1. Balanitis

Balanitis is usually caused by a bacterial or fungal infection and manifests as redness, swelling, itching, red spots, or white discharge on the glans penis. It may be related to excessive foreskin and poor local hygiene. You can use drugs such as clotrimazole cream, erythromycin ointment or compound ketoconazole cream as directed by your doctor. It is necessary to keep the perineum clean and dry every day and avoid scratching.

2. Allergic reaction

Contact with allergenic substances such as condoms and detergents may trigger an allergic reaction, causing red papules on the glans penis and severe itching. Stop contact with allergens immediately and rinse the area with clean water. The doctor may recommend oral loratadine tablets or topical hydrocortisone butyrate cream. In severe cases, dexamethasone injection may be required.

3. Fungal infection

Candida albicans infection is common in patients with diabetes or those with low immunity. It manifests as dense red spots, white film-like material and burning sensation on the glans penis. After diagnosis, miconazole nitrate powder, nystatin tablets or fluconazole capsules need to be used for treatment. Partners need to be examined and treated simultaneously to avoid cross-infection.

4. Contact dermatitis

Prolonged contact with urine, sweat, or chemical irritants may cause contact dermatitis, a condition characterized by well-defined erythema and papules. It is recommended to wear pure cotton underwear to reduce friction. Your doctor may prescribe calamine lotion, mupirocin ointment, or oral cetirizine drops to relieve symptoms.

5. Trichomonas infection

Trichomonal urethritis can be transmitted through sexual contact. In addition to red spot itching on the glans penis, it is often accompanied by increased secretions from the urethral orifice. The secretions need to be checked and treated with metronidazole tablets, tinidazole suppositories or ornidazole capsules after diagnosis. Sexual intercourse is prohibited during treatment, and partners must take medication at the same time.

Daily care should be taken to clean the perineum with warm water every day and avoid using irritating lotions. Choose breathable cotton underwear and change them daily. During treatment, it is forbidden to scratch the affected area and avoid eating spicy and irritating foods. If symptoms continue to worsen or ulcers, pus, etc. appear, you must seek medical attention immediately to check for sexually transmitted diseases such as syphilis and genital herpes. It is not recommended to self-medicate before a clear diagnosis is made to avoid masking the condition.
