On Feb, 12, 2007. I wake up with Continuing sound like whistle on my right ear I think this will disappear shortly, but it stay up to now. After three days from the starting sound, I went to clinic and the doctor checked me and give me medicine tablets for five days (DIMENHY DRINAT 500) I use it Thursday and Friday but no improvement , Does any have any idea, because the sound make me unstable on my head?
