Worst I did was hit my head on an old p50, hit my head on the latches on the swinging doors. Ouch. I bleed bad on that one, walked into a stop on the area thinking I would clean up the wound. Turns out I was covered in blood and they freaked out, kind of funny looking back at it.
Ahhhh, that reminds me of a similar injury of mine. This was a while back when I was still slinging boxes in trailers. I was hopping up into a drop-frame pup with all of the flaps down. My head proceeded to collide with the fan/blower that was installed at the top corner of the bay door. Hurt like hell, but I got over it and continued to load. It was hotter than hell that day and I was already drenched from head to toe. I did not feel the stream of blood running down the back of my head, down my neck and back. I was wearing a white tank top that day, and had my supervisor not seen the stain, I would have never have known until I got home. He was kind of freaking out. So I proceed to the bathroom and got to see the damage. There was a triangular blood stain almost the width of the top of the shirt that narrowed down to about the width of a 2x4 at the bottom. More stain half-way down my ass.
Who knows how much blood that was, but I felt fine. I did not need stitches either. Wish I took a picture of it....was pretty horrific. But your head bleeds like crazy anyway.....
I also did not report it like some people here probably would because I'm not a big p*ssy.
