The Black Hills Stock Show is a place where sore legs are part of the experience. Long days on concrete floors, hours of walking, and only brief pauses before moving again make discomfort feel normal. That environment made it an ideal setting for a live Doc Talk conversation about a condition that often hides behind everyday aches and fatigue.
Broadcast from the Stock Show floor, the episode featured interventional cardiologist Dr. Joseph Tuma discussing peripheral vascular disease, a circulation problem that affects far more people than many realize. Early in the conversation, Tuma shared a statistic that immediately reframed the topic.
“So statistically, it’d be ten to twenty percent of people have, you know, some version of peripheral vascular disease,” he said. “And, you know, a lot of that, the majority of that’s actually asymptomatic.”
That means many people are walking around with the condition without realizing it, while others feel symptoms but don’t connect them to a medical issue.
Peripheral vascular disease sounds complex, but the underlying process is familiar. It is caused by plaque buildup in arteries outside of the heart, driven by the same cholesterol-related mechanisms that cause heart disease. Over time, LDL cholesterol deposits into the artery wall, calcifies, and narrows the vessel, gradually reducing blood flow to parts of the body such as the legs, kidneys, abdomen, arms, and neck.
This process often develops quietly. For years, arteries can narrow without causing noticeable symptoms. Eventually, though, the reduced blood flow becomes enough to interfere with daily activity, especially movement.
One of the biggest reasons peripheral vascular disease goes undetected is that its most common symptom feels ordinary, particularly in physically demanding communities. Leg pain is easy to explain away. Many people assume it’s a normal part of aging or the result of long workdays spent on their feet.
What matters most is how that pain behaves. In peripheral vascular disease, muscle pain typically appears during walking and improves with rest. A person may walk a certain distance, feel cramping in the calf or thigh, stop briefly, then continue once the pain subsides. That pattern is a key indicator of limited blood flow. Pain that only improves when sitting or leaning forward is more often related to spinal issues rather than circulation.
As the disease progresses, symptoms can intensify. Some individuals develop pain even at rest, especially at night when lying flat. Without gravity helping blood reach the legs, circulation becomes even more limited. In later stages, poor blood flow can lead to skin breakdown, ulcers on the feet or toes, and wounds that heal slowly or not at all. At that point, the condition becomes urgent, with a real risk of infection and amputation if circulation is not restored.
The risk factors for peripheral vascular disease closely mirror those of heart disease. High blood pressure, diabetes, high cholesterol, sedentary lifestyle, poor diet, and smoking all significantly increase risk. Family history also plays an important role, particularly in how efficiently an individual’s body processes cholesterol. Some people tolerate higher cholesterol levels without plaque buildup, while others develop arterial disease much earlier.
When peripheral vascular disease is caught early, treatment often does not require procedures. Instead, care focuses on medical management and lifestyle changes. Lowering LDL cholesterol, controlling blood pressure, managing diabetes, quitting smoking, and committing to regular walking can significantly slow disease progression. Even walking that causes discomfort can be beneficial when done carefully, allowing rest before continuing.
Medications are a cornerstone of early treatment. Statins are commonly prescribed to lower LDL cholesterol and reduce plaque formation. Blood thinners, including aspirin and newer medications, can lower the risk of vascular events affecting the heart, brain, or limbs. Because the disease process is the same throughout the body, treating circulation in one area often improves outcomes elsewhere.
When symptoms continue to worsen despite medical therapy, procedures may become necessary. Advances in vascular care have transformed what those interventions look like today. Most cases can now be treated with minimally invasive, catheter-based procedures rather than open surgery. Through a small puncture in an artery, doctors can guide specialized tools to clear plaque, widen narrowed vessels, and restore blood flow. Many patients are able to return home the same day.
Screening plays a critical role in preventing late-stage disease. Simple tests, such as comparing blood pressure readings in the arms and ankles, can quickly identify circulation problems. Ultrasound imaging can detect blockages or aneurysms without invasive testing, often at relatively low cost.
One of the most important takeaways from the live discussion was that peripheral vascular disease doesn’t always present in textbook fashion. As Dr. Tuma noted, “Not everybody reads the textbook.” Some patients describe classic cramping, while others simply say their legs feel tired or heavy.
In a setting defined by endurance and toughness, that message resonated. Paying attention to subtle changes and speaking up early can prevent far more serious consequences later.
