The most recognizable sign of varicose veins is a gnarled, blue or purple vein just under your skin’s surface. Symptoms include: Bulging veins: Twisted, swollen, rope-like veins are often blue or purple. They appear just below the surface of the skin on your legs, ankles and feet. They can develop in clusters. Tiny red or blue lines (spider veins) may appear nearby. Heavy legs: Muscles in your legs may feel tired, heavy or sluggish, especially after physical activity. Itching: The area around varicose veins may itch. Pain: Legs may be painful, achy or sore, especially behind your knees. You might have muscle cramps. Swelling: Your legs, ankles and feet can swell and throb. Skin discolorations and ulcers: If left untreated, varicose veins can cause brown discolorations on your skin. Severe varicose veins can cause venous ulcers (sores) on your skin.
