my 22 month son has a swelling under his right eye this is not the first time it has occured but i am not sure what it is; if a eye infection or what? He is about 30lbs and I took him to a doctor who told me what he it is but i can't remember what he said. But he prescribed novartis and chloramphenicol. Can you please advise if it is a eye infection and if the medication prescribed is effective. This is 8 days that he has it but only 5 days of using the medication and the swelling is still the same.
