question: My 6 year old daughter fell off of a deck about 4 feet from the ground and landed directly on her right butt cheek onto the end of a 2x4 board.  She got a really bad bruise.  It took about 3-4 weeks for the bruise to completely go away.  Now, all of  a sudden her skin is indented (about a 3 inch indented line) and you can feel a bunch of scar tissue underneath.  Will this go away?  Should I take her to get it checked out?
