The causes of frostbite create is that the skin is under cold (below Celsius 10 degrees) for a long-term conditions. After skin is freeze, subcutaneous artery contract, after a long time the blood vessels produce paralysis and expansion, make venous blood almost does not flow, resulting in localized poor circulation, subcutaneous tissue cause malnutrition, and even subcutaneous tissue necrosis may occur. The frostbite affects our body, so we should get rid of frostbite through home health care.

Two grade of frostbite: If the frostbite is seriously, time of small artery contraction is too long, tissue damage seriously, and then the blisters or bullae will occur on the basis of erythema, and show clearly structure, broke blisters and formed the erosion and scab, fluid leak out.

Three grade of frostbite: Because the tissue occur necrosis for the cold , so the ulcers format.
