Differences between claudication and rest pain

Can you please tell us the difference between claudication and rest pain? Certainly, so claudication is pain in your muscles when you exercise or walk relieved by rest. Rest pain is pain created by lack of blood supply to your muscles when you're sitting still, so it's a much more severe pathology and rest pain is included in the classification or the category of critical limb ischemia. If you have critical limb ischemia you're at risk imminent risk of losing your leg. That's not the case of claudication at all. In terms of claudication, the mainstay of treatment is outpatient therapy, risk factor modification, being on the right medications. In terms of critical limb ischemia, including rest pain. So rest pain is typically a pain in your toes and it can be in the daytime or it can be just at the night time. We call it night pain and if you do have this then it's an urgent situation and you need to have treatment immediately to improve the blood supply to your feet, at least within timescale of a couple of weeks, depending on how severe your symptoms are. So two ends of the spectrum, I would say, to do with peripheral vascular disease. Claudication will be the mildest end of the spectrum. Clearly not an insignificant disease, but on the milder end of the spectrum of peripheral vascular disease. And rest pain would be on the severe side and indicates imminent potential for losing your leg.
