I've had a small lump/spot on the side of my testicle area appear, then it disapeared again, at first it seemed it couldn't be popped however i thought it was some type of bite so i left it alone. It has just come back, slightly bigger and is poppable now, and has some pain when squeezed. When i popped it a little bit, at first some (white stuff) not cum, came out of the spot and then later on a little bit of blood mixed in. Im scared to go see adoctor so any help/advice would be helpful
