I have blocked ears constantly. I can pop them by yawning, but then after 10 seconds, they are blocked again. I saw an ear, nose and throat specialist and he did several tests, pressure, hearing etc., Said hearing perfect, no discharge or infection, ears very clean. However said that I need to relax as I have over stretched the vestibular tube?? by yawning and swollering too much and now I need to relax so the tube can go back to normal. I have itchy ears inside and the noise from both ears is like amphlified and hearing is difficult when there is a lot of background noice. There is a constant humming sound from my ears. I am wondering how long does it take to go back to normal. I have no cold, no allergies, never had an ear ache in my life. My doctor has prescribed my valium to have a night to help with relaxation and sleep.
