Your ears are designed to clean themselves, but excess wax can build up in them over time causing itching. You may also experience hearing loss on one side. It is advisable to avoid using cotton buds as they can actually be very dangerous and even damage your eardrum and hearing. They can often push wax further down the canal, worsening symptoms. They can also cause unintended trauma to the ear canal or drum. It is best to see an ENT specialist for further advice and professional ear cleaning.
