Hi. sometimes i've pain on my testicles(not so usual, 1-2 hours max if i have a rest), mostly it happens when i work a lot with my laptop. When i made self exam to my testicles i see nothing wrong but there are 2 lumps on top of 2 testicles(each got one) and there are 2 lumps behind 2 testicles(each got one but theese are like vessels) . There is no cancer in my family. Are theese lumps usual for testicles or should i go urology to check em?
