Why is it that I can't laugh, smile, squint my forehead, or even grin without getting dizzy spells? (Started after a serious concussion I had going on 5 years ago)... Back in 2016 I was assaulted and was thrown into a concrete wall busting my head(right above left eyebrow) off of the wall. I was out cold for a couple seconds and woke up dazed and confused about what had happened. All was alright up until a few years ago when I noticed my symptoms weren’t going away and had gotten worse. I have drastic mood changes, depression, can’t laugh/smile/grin without getting extremely dizzy to the verge of passing out…can’t concentrate worth crap anymore, have constant headaches and forehead pressure, and have noticed I am getting more sensitive to loud noises. What could it be/what should I do?
