Hi, I'm 16 years old, and roughly 2 years ago I fell off my bike, I got a rather large cut on my leg, 2 days later I had this lump form about 2 centimeters away from the cut, at first I thought it was a rock lodged under the skin, but then about 2 weeks after that I squeezed the lump and a lot , about a teaspoon, of fairly hard thick white cream cheese looking stuff come out of the lump... And I thought that would be the end of it, but no it stayed! Ever couple of weeks I can squeeze more of the white stuff out of it. There's no blood, it's numb, I don't feel any pain, and I don't know what it is, oh, and it's like open, it doesn't scab over, and the skin hasn't grown over it , nothing, its just there, and the white stuff does not smell... Any help?
