Sock Marks on Your Legs: What They Could Really Say About Your Health

Many people notice indentations on their legs after wearing socks, which are usually harmless. However, persistent or asymmetrical sock marks—especially with swelling, heaviness, or additional symptoms—can signal health issues ranging from dehydration and fluid shifts to venous problems, and in rare cases kidney disease or heart failure. Practical steps include wearing properly fitting or compression socks, elevating the legs, staying hydrated, and reducing salt intake. See a doctor if marks worsen, are unilateral, or coincide with shortness of breath or significant leg swelling.
