Why is it itchy on both sides of the testicles?

Itching on both sides of the testicles may be caused by scrotal eczema, tinea cruris, contact dermatitis, neurodermatitis, pubic lice, etc. It can be treated by local cleaning, topical drugs, oral drugs, etc.

1. Scrotal eczema

Scrotal eczema may be related to local moisture, sweating, allergic constitution and other factors. It usually manifests as skin erythema, papules and severe itching. Patients can follow the doctor's advice and use glucocorticoid ointments such as hydrocortisone butyrate cream, mometasone furoate cream, or calamine lotion to relieve symptoms. Keep the perineum dry every day and avoid scratching.

2. Tinea cruris

Tinea cruris is usually caused by a fungal infection and presents as annular erythema with scaling and itching that worsens at night. Antifungal drugs such as bifonazole cream and terbinafine cream can be used externally. In severe cases, itraconazole capsules need to be taken orally. Parents should pay attention to disinfecting children's clothes and avoid sharing towels with others.

3. Contact dermatitis

Contact with laundry detergent, chemical fiber underwear and other allergens may cause local skin redness, swelling and pimples. It is recommended to stop using suspicious items immediately, rinse with water and apply hydrocortisone cream. Parents should choose pure cotton breathable underwear for their children and rinse thoroughly when washing.

4. Neurodermatitis

Long-term scratching or mental stress can lead to lichenification of the skin, forming a vicious cycle of itching and scratching. Halometasone cream can be used for a short period of time, combined with loratadine tablets to relieve symptoms. Patients should avoid hot water scalding and cut their nails short to reduce skin damage.

5. Pubic lice

Pubic lice infestation can cause large blue spots and severe itching, and the worms or eggs can be seen with the naked eye. Use benzyl benzoate lotion after shaving your pubic hair, and wash your underwear in boiling water. Sexual partners need to be treated simultaneously to avoid cross-infection.

You should choose loose cotton underwear for daily use to avoid friction from prolonged sitting and strenuous exercise. When bathing, clean with warm water and avoid using alkaline soap. If itching persists for more than 1 week or exudation or ulceration occurs, you should see a dermatologist promptly. During the treatment period, alcohol and spicy food are prohibited. Maintaining a regular schedule will help skin repair.
