I fell on the pavement last week. I have a swollen hard area just below my knee cap on the proximal end of my tibia. I can walk on it and I can bend my knee though there is some twinge of discomfort. When I place any pressure on the swollen area(such as putting my leg/knee up on very soft bed to get in it) there is a great amount of pain. The lump appeared immediately after I fell and has not reduced or really gotten any better. There is no obvious bruising, just scrapes/lacerations to area.
