I took a pretty heavy fall at football practice a little over a week ago. Fell about 3-4 feet right onto my lower back. The pain at first was awful and it hurt extremely bad. Walking and moving was painful, and it kept this way for about 2 days. It slowly got a LITTLE better and I am able to walk and run a little. But I have a bit lump right on my spine. Kind of squishy. Hurts to press it and bending/moving hurts bad. I cannot bend over all the way and most movement hurts, what is it?
