Hey there. I have a question regarding a small bump on the right side of my left kneecap. I m not exactly sure if it s just a bump or a mole. It s the size of the eraser of a pencil, I guess. It appeared around two years ago. I m thinking that it s just a regular mole, but I can t be so sure. It stings whenever it gets touched suddenly or like when I m touching it with my nail. If I m just pressing down on it with the pads of my fingers, it doesn t hurt at all. When it gets touched suddenly, the hurt is quite too much, not too much I guess but I often stop walking or stop doing what I m currently doing because it hurts too much. The color of the mole is quite darker compared to the skin around it. Is it dangerous?
