hi, i am a healthy 25 years old male with a healthy sexual relationship with my long term girlfriend. However recently I have been having slight pain in my left testicles, so I went to my GP and she did an examination of my left testicles. She said that my left testicles had slowen a bit but there was nothing to worry about. However, the thing that worries me is the dull pain which is not very sever but remains as it has been a few days since it start hurting. Secondly, my family has a history of cancer, though its not completely related to my question but what are the chances that I might have testicular cancer or something related?
