My poor head...

Well I was working last night and well I got the big whack on the head... Ouch... Sss... Well in work we were talking about something and I was being sarcastic one and then I needed help with something to reach and one worker bigger than me picks me off the floor so fast that I didn't realize my head was close to the hoods and then WHAM!! I felt dizzy then when he put me down I couldn't stay on my feet. He realized he just slammed my back of my head and was like oh...bleep. He tried to check me out if I was Ok but I kept pushing away although I was dizzy my manager and the other co worker was asking me if I was Ok and I was like.. Oh I'm Ok.. Ow!! I lean on the wall til the spinning stopped and a headache went in that I had to fight it to stay awake after awhile the dizziness went away but felt pain but I made it. If I touch it it hurts. The co worker asked me if I was angry with him for slamming my head so hard. I said no. Luckily I have a rough head and I'm use to it. Well I'll see if I have a swell on my head wish me good luck... Ah man... I had to stay up like 5 hours to make sure I'm fine...
