Talk to Urologist on Bumps On Testicles

I’ve had these bumps on my testicles for years and it’s a recurring issue that I would like to end. There are multiple bumps that vary in size, they don’t cause any pain or discomfort, sometimes they grow or shrink in size, when puncture it releases some type of pus(the pus isn’t as liquid as pus normally it as it’s more like a paste or something). I don’t know what it is or how to treat it.
