What does intermittent claudication refer to?

Intermittent claudication specifically describes a condition characterized by muscle pain, particularly in the calves, that occurs during physical activity such as walking and is relieved by rest. This pain arises due to insufficient blood flow to the muscles, usually due to peripheral artery disease, which restricts oxygen delivery during exertion.

The condition is significant because it often serves as a warning sign of underlying cardiovascular issues. Understanding this concept is crucial for recognizing symptoms related to vascular health and for planning appropriate interventions.
