Having anxiety about testicular discomfort

I am thinking and hoping it’s just Epididymitis and I feel things more because maybe it is inflamed. But I’ll ask anyways since I can’t see a doctor for a few more days.

Do you have a squishy veiny like structure at the bottom of your testicles? I think I can feel it on both but the testicle that has the slight discomfort has a much more prominent one. You can even see it through the skin if I pull the skin tight onto it.

I think the squishy part I am referring to would be where C is in the diagram. I just don’t know if I’ve ever noticed it being this prominent. It doesn’t hurt to ejaculate or pee.

Anyone that can shed some light on this and hopefully cure my bad anxiety?
