Hey james, i got in a snowboarding accident about 3 months ago. I hit my head really hard and was knocked out for about 5 min.(somehow made it down the mountain)... i feel the same way especially the dizziness and nausea! It feels like theres something wrong on the inside of my head..but its extremely hard to explain to my peers.. ive felt fine a week ago and i went out last weekend and after that ive beeen feeling bad the whole week.. back to my normal symptoms..its just really frustrating to live with because you just want to feel better. i hate the feeling of having to vomit and feeling faint, but i never do either of them..also the ringing in the ears can be quite annoying.. i feel like its going away but it just really gets me down.. i play soccer at a very competitive level so this injury is really holding me back...i hope you feel better!
