It's somewhat hard to describe, but for the last day and a half, a dull ache can be felt whenever I move the right testicle. Not a sharp pain, but it almost feels like maybe I hit it somehow without knowing it or something, and it's hard to locate exactly the source of the pain.

I tried looking up things online to see what different conditions there are, but nothing seems to really cover a "dull ache," so it's kind of bothering me. Any help would be fantastic.
