Hi, i have muffled hearing in my left ear. i am almost certain that it is a build up of mucus in the eustachian tube. i have just come from the end of the flu, after 6 days. how long does it take for the eustachian tube to clear? thanks.

It depends : It depends On things like your specific anatomy (how vertical your Eustachian tube is), how hydrated you are , other medications you are taking, etc. if not improved in a few days try irrigating your sinuses with a saline rinse daily. If any pain, swelling or discharge of the ear occurs go to clinic

Varies: Fluid buildup is not uncommon and its resolution depends on many factors. The underlying illness may have triggered swelling in the Eustachian tube that must resolve. Co-existing issues like allergies can delay resolution. In younger patients with smaller structures it is not uncommon for it to remain for 3-4 wks.
