I have a small bump on my scrotum. It doesn't hurt normally, only when I tried to pop it. I managed to do so, and at first the white stuff that comes out of pimples came out. After that, just a little clear liquid, which isn't normal. It doesn't look like a pimple, as it doesn't have a white or black head. It's just kind of a bump. Is it a cyst? Or is it just a pimple without a head? Someone please help! I was really worried at first, until it got a little smaller when I popped it, and it hasn't regrown. There's only one, but others may come. Should I be worried? Or is this normal? By the way, I'm 15 years old.
