Peripheral vascular disease (PVD) claudication is characterized by specific types of pain experienced by patients, especially during physical activity. This pain typically arises from insufficient blood flow to the muscles during exertion, leading to symptoms that often improve with rest as blood supply returns to the affected areas.

Severe pain that is continuous would not be typical of PVD claudication. Claudication pain is generally described as intermittent and occurs with activity, improving with rest. Patients may experience worsening and progressive pain over time, particularly as the disease advances, but this pain is not continuous. It is also important to note that claudication can present bilaterally or unilaterally, depending on the level and extent of vascular occlusion.

The characteristic features of PVD claudication highlight that continuous and severe pain is more suggestive of other conditions, such as acute limb ischemia or neuropathic pain, rather than the claudication seen in PVD.
