Why does frostbite recur

summary

Chilblain is a kind of sore born in a long-term cold environment. Therefore, after getting chilblain, we should take good care of it, otherwise it will become more and more serious, and some will often relapse. Here's why frostbite recurres.

Why does frostbite recur

First, the occurrence of frostbite is related to cold and damp in winter. Cold causes vasoconstriction, local ischemia, abnormal metabolism, long-term vascular paralysis, dilation, congestion, plasma leakage, causing local edema, blister formation, and even tissue necrosis. Limb blood circulation, lack of exercise, malnutrition, anemia, autonomic nerve dysfunction are also the causes of chilblain.

Second: once frostbite occurs, the tissue will be damaged. In spring, summer and autumn, the human body will repair it by itself. However, it is difficult to completely repair it within six or seven months. Therefore, it is easy to relapse the next year. There are also studies that people who are prone to chilblain have lower skin surface temperature and worse microcirculation of extremities than normal people, often accompanied by peripheral microvascular malformations.

Third: they have a high level of cryoglobulin in their blood. When they encounter cold, they will condense and cause peripheral circulation disorders. These genetic and physiological factors are different from ordinary people, which are also the reasons why some people have chilblain every year.

matters needing attention
