Earlier today I (15) noticed a lump about pea sized on one of my testicle. It was painful when I touched it. However, after that I'm not sure why but I decided to squeeze it, I felt something burst/pop and after that it started oozing out some liquid that first appeared white but red, slightly yellow or clear on the tissue. The lump decreased in size, was less hard and also hurts slightly less. Can testicular lumps do that and what just happened?
