𦻠Wax Build-Up or Eustachian Tube Dysfunction? I am seeing more people who believe they have a build-up of earwax, but their symptoms may actually be caused by Eustachian Tube Dysfunction (ETD). The two can feel very similar β both may cause:
- Muffled or reduced hearing
- A sensation of fullness or pressure in the ear
- Occasional popping or crackling
- Discomfort or imbalance
However, the causes are different. Wax build-up blocks the ear canal, while ETD affects the small tube that connects the middle ear to the back of the nose. ETD is often linked to colds, allergies, or sinus issues.
If youβre unsure, a professional ear examination can help identify the cause and guide the right treatment. At East Coast Ear Care, we offer safe, mobile ear assessments and care across Edinburgh and the Lothians.
