umm well i asked alot of my friends about this and they have said when they have puked or coughed hard it's happened to them as well it's a sharp kindda sting almost like a needle kindda thing i'll say again it seems like a muscle contracting to quickly or something along those lines. i mean u could go to the doc but im sure he's gonna say nothing to worry about.

lol that would be a hell of alot of guys with hernias damn can it be that common?? i relate it to working out if anyone has worked a muscle out so much that it locks up on u. the longer u let it go the worse it gets it starts feeling like a muscle is ripping it's that sting that u feel.
