I fell on the ground?!

I fell on the ground?

and i used my hands to stop me, the only part that is like hurting is my thumb, i can see like some parts of blood inside, i mean if you look at my thumb, you can see like purple, like 1 cm then interval then another 1 cm, i think its internal bleeding? of my thumb is that possible, i just fell on concrete, likie slamming my hand on concrete

OUCH! I have had that before it hurts! sorry! i have nothing else to say ..but, I hope it gets better soon!
