Peripheral Vascular Disease (PVD) occurs when there is a damaged or blocked part of the veins that carries blood to the limbs. PVD is often caused by a blood clot, which weakens the wall of the vein and slows the blood flow.
Veins can be damaged or weakened in several ways, including trauma to the veins or an extended period of bed rest or inactivity. In addition, smokers and obese individuals have a higher risk of developing blood clots and/or PVD. Women who are pregnant or are using birth control pills also face an increased risk of suffering from PVD.
The first symptom of PVD is typically pain in the area where the clot has formed, whether it is deep or just near the surface. Other symptoms include swelling, redness and warmth to the touch.
