The other night I woke up after experiencing "flashes" of light and loss of sound. I laid there a moment and had a few more of these "episodes" Then they finally went away-I didn't have a headache but felt like there was pressure when the thing happened-sound returned after the pressure subsided. Does anyone have any input on this? I have a Doctors appointment coming up, but would like to know if other people have experienced the same thing. Thanks!
