i am 18 years old and ever since i have been around the age of 8, my right testicle becomes EXTREAMLY large compared to the left. for some reason it seems to happen more at night. Everytime i went in for a physical, the doctors never said anything about my testicles being abnormal, but my testicles were never large during the physicals because they were all in the morning. I dont think it is testicular cancer because i have read online that told me to take a warm shower and check for any lumps but i never have any lumps. I feel like it is not even my testicle that is large, it is something above it that is becoming large and when i mean large, it can seriously get to the size of a tangerine (not my testicle itself but above my testicle). and i can still see the testicle seperatly from the large abnormal growth, but there is no pains or anything like that, it just feels very heavy and weighs down my sac. someone please help me, i have had this problem for a very long time and i want to get to the bottom of this, thank you.
