Hello,
Varicose veins in testicles needs to be treated with varicocele surgery or varicocele embolization in which a tube is inserted into the groin and then guided under x-ray or ultrasound to the varicose veins. You should get it examined from a urologist and discuss these two treatment options.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
