Since yesterday my right ball has been hurting me but the pain is very minor. Its just a little pain. But I'm worried. Is it serious? And my right now seems lower than the other if that rps? Thx.

It matters on how old are you if your 12,13,14 its normal for puberty growing if its very minor as you mention if your older its due to veins pain for sitting or standing long times... if you feel or see a bulge or like worms in your testicalss then its varicosed veins or dilated veins its harmless if it comes with no pain , but tell me does the pain come if you hold the testicals like hurting somewhere above the testicals in the abdomen ?

One is usually lower than the other. If the pain keeps on after about 4 or 5 days, I would call a doctor for an appointment. It might not be anything serious, but it's safer to have it checked out. Good luck.
