Cerumen irritation: Cerumen in the external auditory canal may be in the form of flakes or flocculent. If a small amount of cerumen falls on the surface of the eardrum, the cerumen will move with it when chewing, talking or exercising, thus causing itchy eardrum. 2. Otitis externa: Otitis externa is usually caused by bacterial attack due to long-term improper ear pulling and water in the ear canal.
