The Eardoc is a simple and easy to use device to treat ear infections and ear pain. To understand better how the Eardoc works, here’s a short review of what middle ear infections are: An ear infection is a common condition that affects the middle ear, usually caused by bacterial or viral infections. In most cases, an ear infection involves blockage of the Eustachian tube (a narrow passage in charge of draining fluid from the middle ear and equalizing pressure between the middle ear and the surrounding environment). When the Eustachian tube is blocked or not functioning properly, fluids accumulated in the middle ear press the eardrum – causing severe pain. The fluid is also a substrate for bacteria growth – causing the infection.The Eardoc uses the body’s own healing ability to cure the ear infections. The Eardoc assist the body to drain the excessive fluid and air from the middle ear, making it easier for the body to fight the infection. The drainage of the fluids and air also reduces the pressure on the Eardrum, relieving the pain in a matter of minutes. Relief is felt after the first use, in 1-2 minutes!
