Might go see an MD

Two weeks ago, I was at an intersection waiting for the light to change and saw the opposite light change to yellow, so I tried to clip in to my pedals and Whack!!!!!!!!  Pedal to shin!  My foot slipped, the pedals rotated and hit my left shin bone.  Obviously it hurt quite a bit, but in my years of riding, it was certainly not the first time.  In the following days, I had a nice bruise, turning all colors of the rainbow.  That's fine, but now there is bump just on the left side of my shin bone that is slightly raised from my skin.  It hurts when I press on it and I have been having some strange sensations down my leg that I have never had before.  Since then, I have gotten in some pretty good runs (6.5-9 miles), so Idoubt it's broken, but does anyone have any ideas of what this could be?
