What should you know about swollen ankles from standing all day?

When you remain upright, gravity makes the leg veins work harder to return blood towards the heart. If the calf muscles are not moving much, fluid may pass into nearby tissues around the ankles. Socks can leave deeper marks, and the skin may feel stretched by the end of a shift. Varicose veins can make this pattern more noticeable.

Mild, symmetrical puffiness that settles overnight is different from swelling that is persistent, rapidly worsening, or linked with other symptoms. Heart failure and chronic kidney disease can present with ankle swelling, while obesity can increase load on the veins. These are possible contributors, not diagnoses based on the symptom alone.

Alternate standing with short walks and seated breaks where your work allows. Flex and relax the ankles, shift weight between the feet, and wear supportive footwear that does not pinch. After work, rest with the legs raised and check whether swelling is reducing. A clinician can advise on compression garments after checking circulation; avoid choosing strong compression without that guidance.

Get urgent care for sudden one-sided swelling, calf pain, warmth, redness, or tenderness, and for any chest pain or new difficulty breathing. Arrange an appointment if swelling is present on waking, does not improve with rest, keeps recurring, or comes with skin changes, reduced urine, or breathlessness when lying flat.

Could my work pattern or varicose veins explain the swelling? Would compression or a workplace movement plan help? What examination or tests would distinguish a vein problem from fluid retention?
