Hello, recently I had some slight testicle pain, more of an ache really, that would radiate from the right to the left and occasionally down my thighs. I went to the doctor, who examined and said he felt nothing out of the ordinary. He reccommended a urine test, which came back normal. About three days after the examination, I noticed a thin vein/tube type thing had appeared near the end of my testicle. It's not very long, and doesn't feel hard or craggy. There is also a hint of a similar one on the left. I think maybe its varicocele or maybe it's just a vein i've brought to the surface from doing a ridiculous amount of worried self examining. There's no swelling and both testicles are soft and normal. I'm just worried it's cancer, even though this is probably unlikely considering its a soft vein that's appeared after discomfort in the testicles, and very recently after a doctor's examination in which he felt nothing out of the ordinary. Right?
