So last week I noticed I had swollen lymph nodes in my neck which soon went down, then I felt pain in the right side of my scrotum and I noticed my testicle (right) had swollen right up, the clinic was closed on the weekend so I gave it a few days to see if it would sort itself, since last week it has gone right down to close to normal size. I'm not sure whether I should still visit a GP or not? Since it's gone down on it's own, does that mean it was just a temporary thing or could it still be linked to Testicular cancer? (I'm 19 btw)
