hi.
generally my right testicle was slightly bigger in size from the left testicle , but 15-20 days back I noticed that my left testicle has enlarged in size from the right testicle 2-3 times , I was also noticing some pain in the vein connecting the testicle ant it was also swollen , after some days , the pain subsided and also the swelling of the vein connecting the testicle also subsided. At present , the left testicle is still enlarged without any pains and it hangs heavy with no fluid accumulation in the sack. A day before the symptoms appeared, i had done some excess masturbation. may it be due to that. i don't remember of any injury otherwise.
