question: hi there.  i fell down some stairs about 4 days ago.  the main areas hurt (with hot to touch bruises), are my right elbow, and very top of my right buttock.  about a week prior to this, i was bending under a table, and when i moved to get upright again, i smashed my tailbone into the corner of the table.  the buise for that has just about disappeared.  i've started getting an odd pain in my abdomen (right side).  it's not a contstant pain.  it comes and goes every minute or so.  it's fairly sharp - but not a terrible stabbing pain right now.  i feel healthy otherwise.  i'm taking a couple of asprin a day to avoid any clotting.  what's the abdomen pain about do yoyu
