How to treat a swollen ear caused by a mosquito bite

The swelling caused by a mosquito bite on the ear can be treated with the following measures: 1. **Local treatment**: Wash the bitten area with running water or soap water, and avoid scratching to prevent infection. Then, apply calamine lotion, compound betamethasone camphor cream, or similar topical medications to relieve swelling and itching. If symptoms are severe, topical corticosteroid creams such as hydrocortisone cream or mometasone furoate cream may be used, but attention should be paid to the duration and extent of application to avoid long-term and extensive usage. 2. **Cold compress**: Wrap an ice pack or a wet towel around ice cubes and gently apply it to the affected area to help constrict capillaries and reduce local tissue swelling. 3. **Oral medication**: If itching and swelling are severe, oral antihistamines such as loratadine or cetirizine can be taken for anti-allergic treatment. Note: pregnant and lactating women should use these medications with caution. 4. **Prevent infection**: If the bitten area becomes broken or ulcerated, apply antibiotic ointments such as clindamycin phosphate gel or fusidic acid sodium ointment to prevent infection. 5. **Seek medical attention**: If symptoms persist or worsen, seek medical help promptly to avoid delayed treatment.
