free flowing mass

[godard31]

Hi, my name is Andrew and I'm a 19 year old male. I found a lump a few days ago behind my left testicle. I made an appointment today to get it checked out. It doesn't seem to be attached to the testicle and I can pretty much move it around. I have no pain anywhere or any other symptoms. I'm guessing the lump is around my epydidmis but I'm not too sure where that is.

Do you guys have any comments or thoughts on this, Thanks alot
