Which of the following is a common symptom associated with DVT?

The most common symptom associated with Deep Vein Thrombosis (DVT) is acute swelling. This occurs because the blood clot hinders normal blood flow, causing blood to pool and leading to swelling in the affected leg. This swelling is often localized and can be accompanied by other symptoms, including pain, tenderness, or a feeling of warmth in the area. The change in venous blood flow due to the clot can result in noticeable swelling, making it one of the hallmark signs of DVT.

Other symptoms like persistent itching, numbness in toes, or cold extremities can occur under different circumstances or related to other conditions but are not as directly linked to DVT as acute swelling is. Therefore, acute swelling is the primary indicator healthcare providers look for when assessing a potential case of DVT.
