Spider vs. Varicose Veins: What are the Differences?
Spider veins and varicose veins have several notable differences, including:
Appearance
Spider veins usually look like discolored webs or branches just under the skin. They are less than 1mm in diameter. Varicose veins are often raised and may look like twisted, bulging ropes. Both types of problem veins can be blue, purple, or red.
Location
Varicose veins usually occur on the legs. Because blood returning from the legs must flow against gravity, these veins become prone to damage over time. Spider veins often occur in clusters, frequently on the legs and even the face.
Causes
Spider veins are superficial veins damaged and expanded by pressure. They are usually cosmetic in nature, but clusters around the ankles can be symptomatic of deeper issues. Varicose veins form when deeper veins in the leg, usually the Greater Saphenous Vein, become damaged. They can become symptomatic and will not improve without treatment.
