What Causes A Burised Lump In The Hand After A Hard Hit?

I hit my forearm quite hard the other day and there is a deep black bruise around what seems to be some kind of knot. Its not on the bone. Its actually on the inside of my arm. Can you tell me what this is, and if I have anything to worry about. Thank you.

after trauma to your arm , the vessels which are supplying to that area and to the distal area also get injured and start bleeding inside your skin .with passage of time this blood will be degraded into its products and so discolour the skin black.if ur distal pulses are ok and there is no progressive swelling then no need to worry dear.it will resolve by itself .thanks
