Hello sir, good afternoon. my daughter, a 5 years old kid had ear pain since last week ( she had running nose and fever two weeks back). when we consulted ENT doctor, she checked and said it is fungal infection. she then cleaned the ear and suggested Oto-AC drops. But the thing is she asked us to clean the ear with Earbud before putting the drops. Is it safe to use earbud everytime?? Could you please clarify on this. thank you
