This morning, at 3 a.m., on my Thanksgiving break, I was wide awake with a piercing sound in my right ear. It was not a constant sound...it was like piercing bleeps in my ear. When I yawned, it would then stay constant. After an hour, it went away, but now it seems to be back. It is so annoying...I'm not sure what is going on. Has anyone had this happen to them?
