Hi, Im a 19 year old male, Ever since I was around 13 I've had this mass/growth/cyst whatever it is on the top of my right testicle. It's strange because I have no pain but when I touch it feels tender. I'm very scared because I've had this for soo long now and barely starting to freak out about it. It hasnt grown to my knowledge but it tworries me soo much. I went to my doctor about two years ago and he examined me and said that he couldnt feel anything abnormal. Its weird because only when the sack is relaxed is when you can see and feel it. I played sports when I was younger and remember long ago getting a helmet to the growing area and being in soo much pain for awhile. Please someone help me, Im living scared of what it could be and worried to see my doctor. :'(
