Earwax is a helpful and natural part of your body's defenses. It cleans, lubricates and protects your ear canal by trapping dirt and slowing the growth of bacteria.
Earwax blockage occurs when earwax (cerumen) accumulates in your ear or becomes too hard to wash away naturally.
Earwax blockage causes discomfort and manifests itself in a number of symptoms, for example, you may complain of ear pain, ringing in the ears, dizziness, impaired hearing in the background of the accumulated mass, and more.
Diagnosis and treatment
Your doctor can remove excess wax using a small, curved instrument called a curet or by using suction while inspecting the ear.
Your doctor can also flush out the wax using a water pick or a rubber-bulb syringe filled with warm water.
If earwax buildup is a recurring problem, your doctor may recommend that you use a wax-removal medication, such as carbamide peroxide. Because these drops can irritate the delicate skin of the eardrum and ear canal, use them only as directed.
