Hi, I was wondering if anyone knew what can cause My hearing to go away and come back as if an on/o0ff switch? for a few years now I have had what i can hear as an 'eeeeeeeeeee' (long e sound) in my left ear several times a day, cant say if everyday but enough times throughout the week. There have been a few times when I have felt some pain,small amount but something, when they occur. Maybe for a couple of years now I feel it has progressed. It's as if you were in a concert and you're hearing fine then when you exit it's like a deafening silence after a couple of seconds you can hear again. Like you are hearing fine then suddenly sound is turned off (deafening silence) like a switch, couple of seconds later sound is turned back on. What is causing this? And also, if whatever is causing this can also affect your vision. Just to see if there is some connection for I have also posted about another problem I have with my vision in another forum. Thank you for any help you may give me.
