question: Hello, I have small lump in the middle of my leg between my kneecap and my shin right near the bone. It's the color of my skin, and is painless. It's only visable when I put pressure on that leg and it's soft (visable due to a slight shift to a whiter hue). When I push it in, nothing happens and there isn't any pain. It seems to completely disappear as soon as pressure is taken off the leg - when I sit down for instance. What the heck is it?
