Hi, I feel like I have 3 testicles in my scrotum? I can feel the 2 real ones but on the far right there is something there that feels swollen. When I push on it, it shrinks like its fluid filled, but its pretty big, like the size of my other testicles. Can someone please help me figure this out even though its very akward. Thanks.

This is a signal that warrants you seeing your physician as soon as possible. It could be many things, but none of them can be diagnosed over the internet.
