dull pain in left testicle?

Suck it up! you're an American be proud of it, we got balls of steel here!

You can have a muscle pinched in your back and that muscle is pressing on the nerves going to your testicle and it is what is causing the pain. Releasing your back muscles is the way to get rid of this pain if you want to try it and here's how: Back: (do from a sitting position) Place your left hand on your left leg next to your body. Place your right hand over your left shoulder and find the muscles next to your spine and firmly press on them and hold. After 30 seconds slowly lower your body forward and to the outside of your left leg, keeping your left arm fairly straight as you do. When you reach your lap remain there for another 10 seconds, release the pressure but rest there for another 30 seconds. Then reverse your hand positions and do your right side. For best results relax your body first by taking a deep breath and exhaling.

Go to the doctor. You may have a hernia or epidedimitis(an infection of the testicle). This is not normal.

if your really concerned about it then go to the doctors. or you might just be hitting your nuts against your leg or something causing it to hurt

did you smack it when you were younger? mention it to the doctors they could say its normal or it will pass, or maybe theyll check it

you should go see a doctor as it is not meant to hurt!
