Critical limb<unk>  includes rest pain and tissue loss. Rest pain Rest pain is a continuous burning pain of the lower leg or feet. It begins, or is aggravated, after reclining or elevating the limb and is relieved by sitting or standing. It is more severe than intermittent claudication, which is also a pain in the legs from arterial insufficiency. Tissue loss Tissue loss is the development of arterial insufficiency ulcers or gangrene due to peripheral artery disease.
