I’ve had a cold and cough for the past 5 days and last night I started experiencing muffled hearing (which I know is common after colds). I held my nose and tried blowing to clear my hearing. My left ear immediately popped but the right ear took a little more and was a half pop (only way I can describe it). I did this a few times and then stopped and went to bed. I woke in the night with a painful right ear and had to take some painkillers I found it worse if I laid down so I was up for a couple hours. When I woke in the morning the pain had gone but the muffled hearing was worse and I had an echo in my right ear. I could hear high pitched voices as an echo. I could also hear my own voice echoing back in my head.
Can anyone help and tell me what has happened? When or will it go? Is there any treatment required?
