question: I fell 4 days ago landing on my right knee, I had a very large lump forming as I was sitting on the floor and skun my knee in the process, I can walk on it but is getting stiffness, and is still warm to touch even though I ve been icing it. I now have bruising forming around my ankle. My knee is very dark purple still and red around the knee cap... what else could I do, maybe I did tear something but am walking ok, just having trouble bending it.
