Two days ago, a ladder fell out from under me and I feel from our second floor railing (about 9 feet) and on top of the metal ladder that fell. I fell on my back. I went to the hospital and they did a full CT scan. Amazingly, nothing was broken and my organs appear to be okay. However, I have 2 enormous bruises. The bruise on the outside of my thigh is extremely swollen and warm. The bruise near my ribs is almost black and extremely painful. Should I worry about any dangerous blood clotting?
