[|Human|] I fell down bottom 2 stairs,lurched forward and then back. I fell on my buttock and the bottom of my spine. This was 2 days ago. I have a nice bruise but no pain when I feel arround the spine but going up staisrs and moving certain ways causes sharp pain. Is this just bruisinfg which will sort itself out I am 72!
[|AI|]  Hello, Well, there is really no way to predict without an x-ray what the status of your skeleton is since it sounds as if you took a pretty could clobber falling to your buttock.  You likely have a condition known as COCCIDYNIA (extremely painful bruising of the COCCYX or tailbone).  This is usually not treatable, even if fractured because it is such a small and inaccessible bone. Whether you may have suffered a bone chip or compression fracture of one of the lumbar vertebrae can only be known if you get an X-ray.  You would be making a smart move to call your doctor in the morning to get an order for some testing and maybe even a good physical exam as a follow-up to what happened. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
