I had a one night stand with a girl i'd never met before an will never see again. we had unprotected sex now two days later my balls are aching all the time. iam worried this could be a std or something.
My son was having pain in his lower abdomen and right testicle. The doctor diagnosed him with Testiculitis. It's an infection in one ore both testicles and must be treated with antibiotics. This was not sexually transmitted because he is only 10 and has never had sex. To be on the safe side, please go see a doctor so you can be properly diagnosed.
