For anal eczema in men, symptoms can usually be relieved by using ointments containing corticosteroids, calcineurin inhibitors, or moisturizing ingredients under the guidance of a doctor, but the specific choice depends on the type and severity of the eczema.

1. **Acute Eczema:** If redness, swelling, and oozing occur, the doctor may recommend short-term use of a mild steroid cream, such as hydrocortisone, to reduce inflammation. It is also important to keep the affected area clean and dry.

2. **Chronic Eczema**: For thickened and dry skin, moisturizing and repairing creams, such as those containing petrolatum or urea, can be used to help repair the skin barrier. If itching is significant, non-steroidal creams such as tacrolimus can also be considered.
3. **Daily Care Instructions:** Regardless of the type of ointment used, avoid scratching, wear loose-fitting cotton underwear, and maintain a light diet, reducing the intake of spicy and irritating foods.
It is recommended to consult a dermatologist for a definitive diagnosis first, and avoid long-term self-medication with steroid creams. Pay attention to anal hygiene daily; clean with warm water and gently dry. With the medication prescribed by your doctor, most symptoms can be well controlled.
