I Fell An My Leg Hit The Step Of The

I fell an my leg hit the step of the stairs 3 wks ago. I had a long bruise on my shin and a lump that is a bit numb. The lump is still there and is a bit numb and itchy and is swollen. Does it take this long to heal the bump on my leg? Should it feel a little numb and itchy? Should I be alarmed that it's taking this long for the bruise to heal?
