Earwax Blockage

Earwax blockage occurs when earwax (cerumen) builds up in the ear canal and prevents normal movement of wax out of the ear. Earwax is a natural substance that helps protect the ear by trapping dust, debris and microorganisms. Normally, earwax slowly moves toward the opening of the ear and falls out on its own.

Sometimes earwax can accumulate and become compacted in the ear canal. This can happen if wax is pushed deeper into the ear, if a person naturally produces more wax, or if the ear canal does not clear wax effectively.

Common Symptoms

Symptoms of earwax blockage may include:

  • a feeling of fullness or blockage in the ear
  • ear pain or discomfort
  • reduced hearing
  • ringing or buzzing sounds in the ear (tinnitus)
  • itching in the ear canal
  • dizziness in some cases

Possible Causes

Earwax blockage may occur when the ear’s natural cleaning process is disrupted. Factors that may contribute include:

  • inserting objects into the ear such as cotton swabs
  • frequent use of earplugs or hearing aids
  • narrow ear canals or excessive ear hair
  • naturally producing larger amounts of earwax
