I've had a chin implant for 2 years and a week ago I tripped up the stairs and fell straight on chin. I had a big bruise for days, which is just fading away. The swelling is almost gone, but right above my chin and under my lip i have a big hard bump. It felt softish, like jelly the first days, but as the general swelling goes down, the bump feels harder and it doesn't seem to go much down. Is it possible that the bump is actually the implant that moved?
