listen, the way you worded you first post even had me wanting to fuck with you, but looks like they did it for me! a couple of things could have happened. you have a nerve that runs by your tail bone that you may have put a little pressure on, i have heard of this several times. a few days and you will be fine. but bad advice about the heat, in my opinion anyway. if you got a little contaminatioin and are beginning to get an infection heat is the last thing that you want. do not totally freak out though bud, i have heard of several people on this board saying the exact same thing about a lump, or a sore tail bone. give it a few days and see how it goes. what where you pinning? i stay away from prop if i can, prop will drop me like a tree man, if what you are doing has prop in it, you may just be real sore. also, how are you storing your gear? dont let it get too cold, if the hormone begins to seperate it will hurt bad as well....try heating your gear up for a while in some hot water (put coffee cup in the microwave with some water in it, and put the gear in after it is hot, you may have to repeat a few times...do not put the gear in the microwave!!!!!). gool luck bud!
