I took a big impact to my shin bone, around 2 inches below my knee, slightly to the left side of it, at first it was bruised and swollen and painful, but i just got on with the game, limping around. many weeks have passed, and now my shin bone feels numb, and i still have a very very tender spot right where i was hit. this was about 2 month ago. there is no bruising or swelling, but there is numbness and pain when i knock it.
