make the medical appointment to get it checked out. orchitis (an infection of the testicle) epididymitis (an infection of the epididymis) as well as other causes need to be considered. having a diagnostic exam will certainly relieve any anxiety about testicular cancer (happens at your age too).
sore testicle with no apparent reason? . for about 2 days not the my left testicle has had a sort of dull ache as if i got hit there earlier. i don't believe i was hit by anything – nothing in particular happened i more just slowly became aware of the soreness. i am a 20-year-old male in fairly good health. i have no history of testicular cancer in my family or any testicular maladies of any sort. should i be concerned? should i wait a couple more days and see if it fades away or is do i need to get this checked out as soon as possible?
