lately ive been having this weird achying feeling in my left testicles. it feels like I have blue balls but idk what it is. when I finish ejaculating, my testicle tends to feel better , but through the day ill feel this achying feeling occur again. Idk what it is, I take ibuprofen here and there and the achying feeling goes away... but again it comes back.. what can this be. please, can someone help I would really appricate it!. thank you
