Well, that about says it. It is very small, but very firm, and most definitely not 100% normal.. or.. at least a natural "supposed to be there" part of my scrotum. As for size, I am unsure of how to explain exactly how big. You know when you were in highschool or somethin and you get bored and pick at an eraser into many small parts? Bout that size. At first I thought it was a tiny pimple, but nope. It don't pop >_< It doesn't hurt, but the fact that it's there gets me on edge. Normally I am not so paranoid about things as minor looking as this but when it's on my manhood I'll call in the bloody platoon to attack the issue.
