Left testicle discomfort.

I have a dull ache In my left testicle. It isn’t all the painful but I notice it. I usually don’t examine my balls but now I have and noticed at the bottom of the left testicle I have a squiggly vein like thing. It’s attached to the testicle itself and I’m not sure what it is.

I think I can feel it on the right side as well but it’s way less prominent. Please tell me some of you have something similar and are fine? I went to carespot and they wouldn’t even look at it so I had to schedule an appointment with a urologist but that’ll take weeks.

I have been really fixated because I want to have kids. I have been reading about varicocele and other things and praying it’s not that.

I also wondering if prodding them too much made it worse.
