hello. about one week back i got hit in the testis by a fast moving tennis ball. there was no swelling and the pain subsided a few minutes later. But since a few days, i have been experiencing uneasiness in my left testicle on touching. moreover it feels like my left testicle has got more veins than the right one after the incident. i have no problem in masturbating, but i am a bit concerned about any underlying problem.
any assistance would be appreciated.
thanks
