I have tinnitus in both ears but it changed back in 2014 and developed a new noise in my right ear but I only hear it when I lay down in bed. I lay down in bed to go to sleep: My left ear is on the pillow and my right ear is facing up. For the first couple of minutes I can't hear any ringing in my right ear but then gradually this extra ringing noise will creep up and appear and then stay there until morning or unless I get up and move around. But then even If I get up, by the time I lay down again it will most times not be there and then again appear. It only comes went I lay down. Even if I use ear plugs during the day for whatever reason I don't hear that extra noise in my right ear. Just again its only when I lay down to go to sleep. I can't really explain it. Could it be a blood thing? Blood rushing to my head and that ear since I'm laying down in bed? Maybe worth taking ginko or vinpocetine as a vasodilator for blood flow?
