Approximately two weeks ago I fell down some concrete steps face first. Almost immediately afterwards, the middle of my lower leg started bruising and became extremely swollen. The swelling was larger than my knee and stuck out more towards my outer leg. I followed RICE over the next day and a half, but it kept swelling and the bruise going darker, which I expected. Now, the swelling has gone down a lot along with the bruising. The area is red now and hard as a rock but is still very tender. I did not at any time have any problems bearing weight on this leg or walking. Two days ago, massive swelling has appeared on that same leg around my ankle along with very dark bruises tinged with red. The bruising over the last couple of days has been spreading completely around my ankle and into my foot. It's getting more and more painful and swollen and is hurting me to walk or move it. There was no other injury after my initial fall whatsoever. My question is, could this be related to my fall? Should I be concerned?
