I have asked my husband to describe this type of pain and I couldn't get him to be more specific than "it f*ckin hurts....makes you puke sometimes." this conversation was awhile ago though, I should have asked him to compare it to other stuff, like getting punched in the stomach, liver shot, etc. I believe he also said the effects were lingering, like it hurt for quite awhile afterwards if it was a big impact.
Seriously is this from some show or something? it's profoundly weird.
