and another thing its not like squishy like a zit its completely solid and under the skin.
im not gonna to lie the first one was difficult to pop and when i finally did it bled for approx. 10 mins
I'm no expert but I have had a similar thing before, and yea I think it's like a zit. If you have too, get a sterile needle and poke it. It might just fill up again or you might not be able to get all the juice out so in that case just leave it alone. Your body will get rid of it eventually.
Could it be something else though? I doubt it would be like testie cancer. You don't get cancer on your nuts when your a teenager.
I do however know that your balls can have a special kind of gland in the hair follicles. One could be infected or clogged.
