I'm 18 years old, I had (notice I saw "had") a friend who always use to mess around like a dumbass and punch me in the groin a lot. A few times hard enough to make me fall down to the ground. Now, my testicles sometimes hurt. It feels either achey or soar and sometimes it just hurts. The pain only lasts for a few seconds though and sometimes the pain can be felt on my left leg.

What exactly could this mean?? Should I see a doctor?? I had my physical done recently and when the doc checked my boys out, he didn't notice anything wrong with them? Am I just being paranoid?

Correction: Notice how I say had. Not "saw"
