Hello! I Noticed A Week Ago That My Purple Veins

Hello! I noticed a week ago that my purple veins on my scrotum have become more noticeable. So basically some context. About 8 months ago I barely cut myself when I was trimming and there was only a few drops of blood and after I noticed a purple vein in that area (left side of testicle). I had no pain, discomfort or anything so I left it alone. Since these 8 months passed, I never had pain there except one time I was wearing pants that are way too tight. However, I looked a week ago and noticed that the purple veins have become more noticeable, before I could see 1-2 purple veins on left side but now I could see one more cutting through the middle and going to the right. These veins are going through the middle from left to right instead of up and down. Also more veins in general have become noticeable which are light red and thin. Also the dorsal vein of the penis have become more noticeable as well. I have small discomfort in area around my balls (but maybe its my groin) but that could be due to me wearing tight pants for work. Apart from that, my testicles are same size and it doesn't feel like a bag of worms.

I wanna know if its a varicocele and whether I should get it checked out? Or could it be from working out? I work out a lot so veins started appearing on the rest of my body but it doesnt make sense why theyd appear down there. Thank you for your help.

The veins in question looks close to this picture http://ihelpbackpain.com/wp-content/uploads/2016/02/SPIDER-VEINS1.png but they are darker and more red than blue
