Good Morning Doctor, From last 2 days, may be due to some insect bite or mosquito bite on my son's right ear it became blackish and little part seems like swollen. Request you to kindly suggest any ointment or cream for faster cure. He says little its paining and sometimes he will rub with his hands on that affected part. My Son's Age is 21 months. Weight - Around 11 kg. Pls find attached images for reference.
