Got Leg Pain? It Could Be PAD

If you have unexplained leg pain, especially after you walk or exercise, you could be one of the eight to ten million people in the United States who suffer from Peripheral Artery Disease (PAD). This condition is often difficult to diagnose, leaving many sufferers untreated, which is a serious problem due to the danger that it can pose.

PAD symptomsWhat is PAD?

Peripheral Artery Disease is caused by a narrowing of the peripheral arteries. While it most commonly affects the legs, it can also be found in the stomach, arms, and even your head. Arteries begin to narrow when plaque, which is made up of cholesterol, calcium, fibrin, and fatty substances, builds on the walls of the artery. The disease restricts the amount of blood flow and raises blood pressure. In severe cases, a blood clot can form and completely stop your blood flow, which can result in a stroke or heart attack.

Risks & Symptoms of PAD

You could have PAD and not notice any symptoms until your disease progresses. Others may mistake their PAD symptoms for another condition. To avoid misdiagnoses and missed diagnoses, it is important to learn the most commonly observed symptoms of PAD. They include:

  • Leg pain during exercise, and also when at rest
  • Leg numbness or weakness
  • Wounds (ulcers) of the legs, foot, or toes that do not heal easily
  • Legs or feet that are cold to the touch
  • Slow nail growth on toes or lack of hair growth on the leg
  • Some men experience erectile dysfunction

Patients are more at risk for peripheral artery disease when they:

  • Smoke cigarettes
  • Have diabetes
  • Are obese
  • Have high blood pressure & cholesterol
  • Are over 50 years of age
  • Have a family history of heart issues or strokes

How is PAD Diagnosed?

Diagnosing peripheral artery disease is painless. And there are many ways to test for PAD, so your health care provider will perform a physical examination to determine which to choose. In addition, your doctor may perform:

Ankle Brachial Index: This compares the blood pressure in your feet to the blood pressure in the arms. It determines if your blood pressure is faltering in one area or throughout the body. Next, there are ultrasounds, which use sound waves to measure blood flow and visualize blockages in your arteries. Alternatively, you may need angiography: you’ll get a colored dye injection in your blood vessels. Then, we’ll trace the dye with an imaging device, so we can follow your blood path and determine where the problems lie. Finally, you may need blood tests to determine if your symptoms are the result of diabetes or other issues.
