Little hard bumps on scrotum

I’ve been having these little hard bumps appearing once in a while on the sides of my scrotum. They are about the size of a pimple, but it’s different from the kind of pimple you get from pubic hair. I don’t think it’s a sexually transmitted disease either because when I cut them with little scissors and squeeze out what’s left of the hard dry substance, it goes away like a face pimple that you’ve squeezed, although it looks and feels different than the kind of pimple you get in the face. My hypothesis is that my body is clearing itself from something that was in my testicles, so, in a way, it would be a good sign, but if someone knows it to be a symptom of something bad, I guess you better tell me.

Anyone else had this? For me, it’s started a couple of weeks after my 20-day water fast, and I’ve been having them for about a year now. It doesn’t hurt and cutting them off doesn’t hurt either. What’s striking about them is that they are hard because their substance is not liquid and they grow out of the scrotum (that’s why I can cut them off).
