Spinal cord minor injury?

[marq]

i was summer salting off of my bed backwards. then i did it and my legs were in the air then they fell forward not backward and my back was crushed and it was making noises the i fell over and i could not move then i try ed to call for help but i couldn't make loud noises. in a few seconds i could move again and the pain wasnt as bad but it has continued to hurt a little to today and that happened 2 days ago. what happened and what should i do?
