For anybody following the saga of my balls, the good news is they don’t think it’s cancer. I have highly unusual balls I’m told, where there’s about 15 small developmental cysts on each that are just chilling and have probably been there a long time (from fetal growth).
Also don’t be afraid of getting your balls checked out, I had three ultrasounds and all were painless and not embarrassing. I have a ton of funny stories too, eg the Windows ultrasound box rebooting for security updates mid scan
