I think I may have busted a blood vessel in my head.
I took a drink of water and it went down my throat the wrong way. I started choking and water came out of my nose and stuff. Now my head hurts.
If you 'busted' a vessel in your head, you'd know it. That would be a major aneurysm, and it would hurt very very badly. The nervous system is very tricky and will mess with you in many ways, just like the subconscience. Your mind might also be playing tricks on you. The mind is a very powerful thing. Sleep on it. If it doesn't feel better in 2 days, go to the hospital.
once I was showing my friends how to swallow whole glass of water in 2 sec (straight to the throat) and I fucked that trick up, whole glass of water went to my lungs, that was real hell, I was choking for like an hour
