I have had this pain spot at end of spine/top of ass crack for a while. I have a high pain tolerance, but this is bothering me too much. It registers in my mind as feeling like a tight spot or nub, but there does not seem to be an actual visible injury to that area.I cannot walk, sit, lay down, or even shift a little without a shooting and stabbing pain there. Even when I find a semi-comfortable position where the pain is at least bearable, there is still a stabbing throbbing pain. It even woke me up from a deep sleep (from exhaustion) only after about 5 hours.When google-ing around I found a site that says this might be about my Coccyx (http://www.coccyx.org). I do not know though (didn't even know I had one of those).

So, my first question is what is it that I have? Do I need to go to the hospital or something for this? And what is a good way to help get rid/alleviate the painfulness?
