Rest pain is typically characterized by pain occurring at what time?

Rest pain is typically characterized by pain occurring at rest, particularly at night in the forefoot or foot. This type of pain is associated with critical limb ischemia, where inadequate blood flow leads to discomfort even when there is no physical activity. Patients often report that they feel the pain at night while lying in bed, and they may find relief by dangling their feet off the edge of the bed or walking around for a while, which helps improve blood flow temporarily.

During exercise, pain is commonly related to claudication rather than rest pain. Claudication occurs due to insufficient blood supply during increased demand, which is not the case for rest pain that persists when the patient is not active. Similarly, pain throughout the day during normal activities and immediately after walking generally reflects conditions that are distinct from rest pain and are often linked to intermittent claudication or other forms of vascular insufficiency.
