Spider veins and stretch marks may appear similar on the thighs or legs, but they’re very different. Spider veins are small, damaged blood vessels that can appear blue, red, or purple, often forming web-like patterns on the skin. They’re common on the thighs and may become painful, especially when standing for long periods. In contrast, stretch marks are scars that develop due to rapid skin stretching from pregnancy, weight gain, or growth spurts.
