I am a 16 year old (Obviously male) Caucasian American. For the past 6-7 days my testicle has had a pulsing type of pain. Recent event have been a person I was very close to died; and I had cut back on masturbation.

Also I have noticed that the left one with the pain is harder then the other one. Not bigger, just harder. And I have NOT been kicked or hit down there recently.

The best way I can describe the pain is pulsing, however it has only effected me when I am either, Standing, Laying down, or walking. I have not run anytime in the winter, and it seems to be more when I am laying down. It doesn't hurt when I sit down though it is uncomfortable, I don't notice it when I am playing video games or hanging out with friends.

Also note that it is not very painful. It feels about as painful as if it I bruised it.
