I am 14 years old and have recently found a small, sack inside my scrotum that isn't attached to either of my testicles. If it's squeezed, it feels like some liquid will squirt through something like a vein and back into some organ or something in the area around my belly-button (lower-chest). Once squeezed the sack will disappear for several hours before returning. I haven't told anyoneabout this yest but am worried that I may have a cyst or cancer. Could you provide me with some possible problems and how to treat them. Also, could you PLEASE e-mail me a response to _[removed]_

PS. THE SACK IS PAINLESS!!!
