Since starting retigabine my tonal component has gone down and I am left with mostly an all over brain 'shimmer' or hiss. It's from the inside out. While that's getting more and more tolerable, I'm left with a feeling of fullness, like an awareness of an area inside my head toward the ear going slightly down to my neck and upwards to my head. Backward a little too. Trying to describe it, I'd say if you hear a loud noise you feel the pain in this area. It's very odd and one of the things that is making it hard to habituate. I keeping wanting to call it brain damage - it feels almost like a bruise inside my skull from the original noise trauma. Is this what everyone feels like? Do you get physical sensation of damage/different-ness as well as an auditory component?
