What are possible treatments and how do I know when it is time to see a specialist about bulging veins in the groin?

I have a cluster of bulging veins in my groin that has been slowly developing over the past decade. There isn't anything like it anywhere else on my body. I don't really like the way it looks and I would prefer that it not get worse. Also, for the past year I have had an intermittent severe itch with no visible rash in exactly this area, and I read that itching can be one symptom of varicose veins. Is that possible? Does this seem like something that a vein specialist could help me with? What are some of the possible treatments? I would be particularly interested in minimally invasive treatments to begin with because of where these veins are on my body.
