Spider veins are a smaller type of varicose veins. They affect your capillaries, the smallest blood vessels in your body. You’re most likely to get these on your legs or face. They look like a spider web; they’re usually blue or red.
Many people with varicose veins or spider veins complain of pain, described as an aching or cramping in the legs. Other common symptoms include tiredness, restlessness, burning, throbbing, tingling, or heaviness in the legs. Pain from these veins is usually relieved by elevating the legs or by wearing support hose.
In women, symptoms may be worse during certain parts of the menstrual cycle or during pregnancy. Less common is swelling, ulcers and a darkening of the skin, especially in the ankle region. Occasionally, varicose veins can form a painful blood clot with inflammation of the vein, a condition called thrombophlebitis.
