Hi, a while ago, I noticed what feels something like a swollen vein on my testicle. It extends from one side of my testi to the other and is quite thin. The lump is hard and painless. I have not noticed any growth. Also, I occasionally get a dull aching pain in my groin above the testicle. My right testicle is also larger than my left. I am growing concerned about this and would appreciate any information or guidance you could give on the subject.
Thanks
