I often wear only one earbud. Recently, I've noticed quieter sounds seem like hearing loss. Can wearing one earbud cause deafness? (Long Nguyen, 40, Ho Chi Minh City)
My son has otitis media. Lately, he has ear pain and can't hear clearly, possibly due to a ruptured eardrum. Can a ruptured eardrum heal without treatment? (Phuong An, 37 years old, Hai Phong)
