Testicular pain

Is testicular pain a good thing or a bad thing? I wonder if it could be a good thing in that your balls know that something is not right and they’re trying to fix things up, or could it just be a sign that something is wrong?

I remember Mew posted a link to a site where it said that testicular pain might be experienced while taking tribulus terestris because the testicles need to get used to producing more testosterone.

Let me know what you guys think.
