The #1 Remedy for Varicose Veins (Venous Insufficiency) – Dr. Berg
Veins that are dark purple or blue
Veins that appear twisted and bulging, often appearing like cords on the legs
When painful signs and symptoms of varicose veins occur, they might include:
An achy or heavy feeling in the legs
Burning, throbbing, muscle cramping and swelling in the lower legs
Worsened pain after sitting or standing for a long time
Itching around one or more of the veins
Changes in skin color around a varicose vein
Spider veins are similar to varicose veins, but they’re smaller. Spider veins are found closer to the skin’s surface and are often red or blue.
