Hello, I was playing bowling last night, as I threw the ball, i heard the most loudest crack in my head. I went all dizzy and swetting a lot, my eyes went all blury for a few seconds. Then i had a really horid pain down the side of my left head going down my face too. Today i woke up and my head hurts a little if i press it in and also i have a banging headache . could you suggest what the cracking noise was pleasee? thankyyou
