Concussion

Hospital right now, you are a fool if you have not gone by the time you have read this. Head injuries are not a joke, I had one once and apparently had a different (violent) personality for a few days. I dont recall anything this other me did, but I am a fool for not getting it not checked out.

Way to drunk for this, but the impact made your brain swoll up, the drunk feeling is your brain touching the inside of your cranium. (or close to)
You could have ehm, brainbleed(no idea of english word) which can cause pressure and even more damage if left unattended.

Missed this. It's called a hematoma, and IF that's what this is and it remains untreated, you can(and likely will) die, and it will start to get very serious soon - 2 days is FAR too long to wait to treat it.
