causes of echoing in the ear
The echo that you are describing could most likely be due to an Eustachian tube dysfunction which is generally seen when you are suffering from cold. The Eustachian tube connects the middle of the ear to the back of the throat and maintains the pressure in the inner ear. When there is an infection or cold, this gets blocked leading to the symptoms.This echo sensation will go off on its own and no treatment is usually required.
