Hello, I am 20 years of age and I have a bit of a problem.
I have noticed in the past few years that I have an odd mass next to my other two testicles. This mass comes and goes and is not painful. It is usually squishy and I can squish it completely. When I flex my abdominal muscles, have a mild constipation or perhaps just don't eat right, it seems to reappear. It's about the size of my other testicles and I recently noticed that if I lay down, it seems to deflate, but when I sit up it inflates again.
I think this may be just some sack of liquid or something, but I was unable to find much help online so I thought I'd ask here before seeing a doctor.
