Final answer:

Varicose veins are enlarged and twisted veins caused by ineffective valves, predominantly affecting the legs.


Explanation:

They commonly occur in the legs, particularly in older adults, females, and those with a family history. Although often a cosmetic concern, severe cases can cause pain, swelling, and skin issues.
