Leg swelling from the knee down

A broad, gradual swelling in both lower legs can reflect dependent fluid or reduced vein return; Varicose Veins are one possible contributor. One-sided swelling after an injury may relate to tissue or joint inflammation. Red, hot, tender skin can indicate infection, while sudden one-sided swelling with calf pain requires assessment for a blood-vessel problem. Heart Failure, Chronic Kidney Disease, Obesity, and some medicines can contribute to swelling in both legs. The appearance should be interpreted with your history and examination.

Compare both legs and note onset, pain, warmth, redness, skin marks, and whether a dent remains after gentle pressure. Avoid prolonged sitting or standing, move gently when comfortable, and support the legs during rest. Protect stretched skin and check feet for blisters or wounds. Do not massage a suddenly painful swollen leg or take leftover medication. A clinician can decide whether examination, blood tests, or scanning is needed.

Seek urgent medical care for sudden swelling of one leg, especially with calf pain, warmth, redness, or tenderness. Call emergency services for chest pain, severe breathlessness, fainting, or coughing blood. Prompt review is also needed for fever with spreading redness, an infected wound, inability to bear weight, or rapidly increasing swelling.

Ask whether the pattern points toward a vein, infection, injury, medicine, heart, or kidney cause, and whether you need testing. Ask what activity is safe, whether elevation or support garments suit you, and how quickly to return if the swelling changes.
