No, you can never grow your veins back but you can get surgery and new veins can be put into your veins system. P.S. My brother got a surgery. He is perfectly fine.
Ofcourse not, you don't see them, your fingernails can't bleed and the body doesn't see a need to put nerves in it.

collateral veins are produced by your body when it thinks it is not getting sufficient circulation from a part of the body. If a part of your body is not returning blood back to the heart from a particular part of the body, your body will grow veins around that area to assisst in circulating the blood. Unfortunately these veins are usually thinner and less organized than the original venous structures. Spider veins are examples of collateral veins. There are collateral arteries as well. When a part of the body is not receiving enough oxygen new arteries will grow around to assisst in circulation. Like veins these are of poor structural quality too.
"Vascular" refers to relating to or involving blood vessels, such as veins, arteries, and capillaries in the body.

There are three major categories of veins: superficial veins, deep veins, and perforating veins. All varicose veins are superficial veins; they lie between the skin and a layer of fibrous connective tissue called fascia.
There are three types of veins, superficial veins that are just beneath the surface of the skin, deep veins that are large blood vessels found deep inside muscles, and perforator veins that connect the superficial veins to the deep veins.
