I hit my shin really hard on a step while getting into a van about two weeks ago, it hurt a lot at the time but i thought it would be fine later on, never thought to put ice on it or anything. It never looked very bad from the outside, there is light bruising and a bump, however despite its appearance, it is still very painful and very sensitive to touch, the bruise and bump have not seemed to change since the i got the injury, and it doesnt feel like its healing. should i go see a doctor or wait a little longer and see if it goes away?
