Unfortunately, I don't think there isn't much you can do about it other than trying to avoid making it more painful than it is already.
Also, pain is pain. It isn't more laughable whether it's in your ass, your feet or your back. Now if you had gotten it from some kind of stupid action on your end, I would probably laugh.
I had a friend who got a testicle twisting (not sure it'd be called like that in english, heh) back in high school. Something he had to go for surgery immediately to get rid off it. When he went back in class on the following week and he told us what happened, some people were making fun of him.
I would have loved to see them in the same situation. Shit must have been horribly painful. :|
Nothing to your level, but I often get my lower jaw like paralyzed for a few seconds when I yawn or open the mouth too wide, like I don't feel it, or rather feel like the nerves in it and a part of my neck turned into stone for a moment.
You'd think I got used to it after years, but it's still a very unpleasant feeling everytime.
