Claudication

Claudication, literally 'limping' (Latin), is a medical term usually referring to impairment in walking, or pain, discomfort or tiredness in the legs that occurs during walking and is relieved by rest. The perceived level of pain from claudication can be mild to extremely severe. Claudication is most common in the calves but it can also affect the feet, thighs, hips, buttocks, or arms. The word "claudication" comes from the Latin "claudicare" meaning to limp.

Claudication that appears after a short amount of walking may sometimes be described by US medical professionals by the number of typical city street blocks the patient can walk before the onset of claudication. Thus, "one-block claudication" refers to claudication that appears after walking one block, "two-block claudication" appears after walking two blocks, etc.
