I Have A Slight Discomfort In My Right Testicle Area.

I have a slight discomfort in my right testicle area. I would hardly call it pain but at two points it was a little bit painful. It almost feels like my right testicle is ultra sensitive in both movement and sound vibrations. It also appears that the space above my testicles to the right is more tender than other side. I do not see lumps or anything to be alarmed about but it certainly doesn't feel normal. Any ideas? I just want to know if it'll pass or if I should get a checkup. I have no experienced any bad pain to this day.
