Here's What It Means If Your Socks Leave Marks On Your Legs — And When To Be Concerned - Yahoo Health

What the report says

HuffPost reports that marks left on ankles or legs after wearing socks are usually common and not automatically a sign of illness. The article cites Dr. Katherine Teter, a vascular surgeon at Hackensack University Medical Center in New Jersey, and Dr. Brintha Vasagar, a family physician in Wisconsin, who said such indentations often occur after long periods of sitting or standing, when fluid can collect in the lower legs.

According to HuffPost, other everyday explanations can include socks that fit too tightly, dehydration or a salty meal, all of which may contribute to temporary swelling. The doctors said people should pay closer attention when sock marks appear along with other symptoms, such as swelling that happens even without socks, skin darkening near the ankles, prominent varicose veins, or leg heaviness, aching or fatigue that improves when the legs are raised.

The report also notes that one-sided or worsening marks may warrant a medical check, especially if they become deeper or last longer over weeks or months. HuffPost says the doctors identified heart failure or kidney disease as possible but more serious explanations in some progressive cases, particularly when other symptoms such as shortness of breath or difficulty lying flat are present. Teter added that sock lines alone are not typically a sign of a blood clot, which would more often involve notable swelling, pain or redness.

For people without concerning symptoms, HuffPost says possible ways to reduce marks include wearing well-fitting socks, elevating the legs, staying active and considering compression socks, especially for those who sit or stand for long stretches.
