I had this problem also early feb this year then the doctor gave me some steroids medicine and the symptoms had been reduced.Now past one week i am also facing the same issue once again. The sounds are louder in my left ear including my own. Unable to hear anything clearly over the phone from that ear. As of now no vertigo or balance problems but ear is continuously making sound like old landlines do when you pull up the receiver to your ear but in a low pitch. PTA and MRI of cp angle also done. See attached. Kindly advise what could be the reason. I am really worried. Thanks in advance.
