I have this vein on the left side too. The vein gets very big on one place and it does look like a varicocele vein. I have not masturbated for about 4 months now (I did have sex tho) but things do not seem to improve. I do not think our body is capable of solving this its self. I also saw several specialists, but none of them can actually do anything. I am wondering if anyone knows of any cases where this problem has been solved.
