what are varicose veins
Varicose veins are veins that have become swollen with blood, leading to a tangled appearance and pain. The swelling in varicose veins arises from improper venous function, leading to inappropriate blood collection. Generally, varicose veins occur in the legs, but they can occur in other regions of the body as well.ymptoms of varicose veins include visible, raised, swollen or malformed âtanglesâ of veins, leg pain, and swelling, and in severe cases, ulcers of the legs. In most cases, varicose veins can be treated by avoiding excessive standing, sleeping with your legs elevated, or wearing support hose.
