Varicose veins of lower extremities
Varicose veins are swollen, twisted veins in your legs that happen when blood flows backward instead of moving up toward your heart.

Varicose veins are veins in your legs or feet that have become enlarged and bumpy because the blood is not flowing smoothly. Normally, your veins have tiny one-way valves that act like doors to keep blood moving toward your heart. When these valves grow weak or get damaged, blood pools in the vein, causing it to stretch and twist.
While these veins are most visible just under the surface of the skin, they are a sign that your circulatory system, which carries blood throughout your body, is struggling to work efficiently in your lower limbs. They can look like blue or dark purple cords and are often felt as a heavy ache in the legs.

- A heavy, aching, or "tired" feeling in your legs, especially after sitting or standing for a long time.
