What are common signs of deep vein thrombosis (DVT)?

The common signs of deep vein thrombosis (DVT) include swelling and pain, particularly in the affected limb, usually the leg. DVT occurs when a blood clot forms in a deep vein, often in the legs, leading to these hallmark symptoms. The swelling is usually localized to one leg and may be accompanied by a sensation of warmth in the area. The pain can manifest as cramping or soreness, often starting in the calf. These symptoms are critical for identification because early detection and treatment of DVT are essential to prevent complications, such as a pulmonary embolism, where the clot dislodges and travels to the lungs.

Other options, while they may represent legitimate medical conditions or symptoms, do not specifically correlate with DVT. Rash and itching are typically associated with allergic reactions or skin conditions, shortness of breath is more directly linked to respiratory issues or circulatory problems that could arise from severe DVT complications, and pale skin may indicate inadequate blood flow or other complications, but is not a direct sign of DVT on its own. Thus, swelling and pain are the primary indicators for recognizing this serious condition.
