Which condition is most likely with leg swelling and leg cramping after prolonged sitting, absent trauma?

• A. Venous Insufficiency
• B. Deep Vein Thrombosis
• C. Cellulitis
• D. Congestive Heart Failure

Answer: (B)

Prolonged sitting slows blood flow in the leg veins, promoting venous stasis and increasing the risk of a clot forming in the deep veins. When a deep vein thrombosis develops, it often presents with leg swelling and aching or cramping, and this can occur after a period of immobility without any injury. The combination of unilateral leg swelling with cramping after sitting is a classic scenario that raises concern for a DVT because it points to a problem inside the deep venous system rather than a superficial or systemic issue. Other options don’t fit this pattern as well. Venous insufficiency tends to cause long-standing or recurrent swelling and a heavy feeling, often worsened by standing and with more diffuse leg symptoms over time rather than an acute cramping episode after sitting. Cellulitis would typically present with redness, warmth, fever, and skin changes over the affected area. Congestive heart failure usually leads to bilateral leg swelling and is accompanied by signs like shortness of breath, fatigue, and rapid weight gain.
