right now my bro has the same thing in almost the same spot...rail was more slick than he thought and he bounced his ass right off the kink. went to the hospital and the doc. told him that it was a hematoma(?), or something like that. just a ton of blood between the muscle layers. anyway, good luck with that one man...i know my bro is in a shitload of pain, the doc. gave him vicodin for it.
