I think I have hernia in the groin. I was masturbating and ejaculated quite forceful but after that (after 12 hrs approx) there was a lump at the top of my right testes and it hurts after i ejaculate (not immediately but after 8 or 10 hrs after that). It is painful when I walk or sit down. If I take 2 paracetamol (500gm each), the pain subsides after 2 hrs. And if I don't masturbate for the next 24hrs the pain disappears only to reoccur after I masturbate again (not immediately but after 8 or 10 hrs after that). Is this a muscle pull or hernia. What should I do? thanks.
