Hi..my Name Is Nina..Im 22 And I Have Recently Fell

hi..my name is Nina..Im 22 and I have recently fell down the stairs 3 days ago, I have very shard pains in my lower back and middle section on my back near my spine. Also I cannot move good at all, I cannot stand without beaning in pain and I can barely sit. I have pretty much been on bed rest since the incident has happen. I would give the pain rate a max 10, I cannot lay down, I cannot turn, I cannot bend down or even get into the car. what do you think this is? what should I do?
