Testicle Injury–Should I worry?

Hello,

About four months ago, I sort of struck/crushed my testicles, mostly the left one. When it happened, I was in pain, but not severe pain for a testicle blow. There was some swelling, redness, and discomfort for several hours, which I didn’t really think much of.

Later, a bruise formed on my testicles, which was accompanied by itching and some discomfort. The bruise eventually went away, but there were prominent blue veins on my testicles. The veins look a lot like the varicose veins some older women get in their legs. They occasionally cause mild itching and discomfort.

Four months later, the veins still haven’t gone away. I haven’t been to a doctor about this because I can’t really go without my parents knowing. The veins haven’t really caused much pain or discomfort, but I’m concerned anyway. Do I have a varicocele? Is it just a cosmetic thing, or will it cause “man problems” down the road? Should I worry or seek medical treatment, or is it too late to do anything?
