Sock Marks on Your Legs Could Be Health Clues
Sock marks on ankles or legs are common and usually harmless, often caused by sitting or standing for long periods, tight socks, dehydration, or a salty meal. However, if the marks come with leg swelling, asymmetry between legs, hyperpigmentation, large varicose veins, or persistent heaviness, they could signal vein problems or, rarely, kidney disease or heart failure. Blood clots are unlikely in this context. To reduce marks, try elevating your legs and wearing comfortable or compression socks, and see a doctor if marks persist or worsen.
