I just joined the site today cause I need to know more about what I'm feeling and if anyone you have gone though this or found away to make it stop, for about 6-7 months now I've been getting a sudden zap or shock in the back of my head it's like losing consciousness for a millisecond and after that my vision is blurry like I'm staring through a screen door and my balence is way off it feels like the ground is bouncing when I walk or like walking in a fun house and I always get ringing in my right ear shortly after , im not on any medication or havent been for 10 years and back then I was put on Aderall and before that Concerta for school, please if anybody has info or somthing that makes this go away let me know I need my life back
