Hey!.. I'm 16 years old, and have 4 bumps on my testicles (2 on each side).. I've had these a few times, but only 1 or 2 each time. This has happened about 3 times. It really hurts when I walk. Yesterday, I tried to pop one, and a reddish-pinkish liquid came out (puss and blood?). Today, the one I popped looks like it's gotten bigger and it looks as if its full of blood!. I'm really concerned about this and I don't know if its something really serious. :-(

Has anyone else had this problem?, and how do I get rid of them?
