Earwax blockage, or cerumen impaction.
Ear wax, or cerumen, is made by the body to help protect the ears. Cerumen is healthy in normal amounts and serves as a self-cleaning agent that lubricates and protects your ears by trapping dirt and slowing the growth of bacteria.
For most people, ears might never need to be cleaned. However, an earwax blockage, or cerumen impaction, can cause hearing loss, fullness in your ears, discomfort or dizziness. If you are experiencing the signs and symptoms of a cerumen impaction, the cerumen can be removed safely by your ENT doctor.
