You know how sometimes you fall and it doesn't hurt, but if it's a GOOD fall, you about kill yourself. Well, it looks like you got a GOOD conk on the head from that sheet rock.
Got smacked by a falling brick once. Discovered the scalp bleeds like there is no tomorrow. Hope you heal up well and quickly. Hope there was no concussion either!
That's old school for sure. My wife tool a nasty fall and opened up about a inch and a half gash on her forehead. Went to the ER and after a CAT scan they used super glue and steri strips to close it up. Sheesh, I could have done that myself (except for the CAT scan) and saved the ER cost
