What should I do if the glans penis is bitten by a mosquito?

The glans penis has been bitten by a mosquito. The following measures can be taken for treatment: 1. **Local cold compress**: Wrap ice cubes in clean cloth and gently apply to the affected area to help relieve itching and swelling. Avoid direct contact of ice with the skin to prevent frostbite. 2. **Medication**: For mild symptoms, topical anti-inflammatory and antipruritic ointments, such as lincomycin and lidocaine gel, can be applied. For more severe symptoms, such as blistering or erosion, topical application of 3% boric acid solution or furacilin solution may be used, followed by application of fusidic acid cream to prevent infection. Under a physician's guidance, creams containing hydrocortisone, betamethasone acetate, or similar ingredients may also be used. 3. **Oral antiallergy medications**: Such as cetirizine or loratadine, which can help reduce allergic reactions. 4. **External application of traditional Chinese medicine**: Herbs with heat-clearing and detoxifying properties, such as honeysuckle or dandelion, can be boiled and then applied externally to provide auxiliary relief for mild inflammation. 5. **Seek medical attention**: If symptoms persist or are accompanied by other discomforts, prompt medical consultation is recommended for professional diagnosis and treatment.
