What are the symptoms of a deep vein thrombosis (DVT)?

Swelling, pain, and redness in the affected leg are classic symptoms of a deep vein thrombosis (DVT). This condition occurs when a blood clot forms in a deep vein, commonly in the legs, leading to these hallmark signs. The swelling happens because the clot obstructs normal blood flow, causing fluid to accumulate in the tissues. Pain often presents as a cramp or ache and may worsen when standing or walking. Redness or discoloration of the skin can occur in the area over the clot. Identifying these symptoms is crucial, as DVT can lead to serious complications, like a pulmonary embolism if the clot dislodges and travels to the lungs. Understanding these key symptoms is essential for early detection and prompt treatment.
