When burned at low temperature, the skin surface is red and hurts like a fire. This kind of minor injury can be cured in a few days. Although some burns have no pain, they form edema, so it is difficult to judge the severity of burns from the surface for a while. But the possibility of deep burns should be considered. Burn should be diagnosed and treated in time. After treatment, burned skin will generally fall off, and new skin will be born after swelling.

If the treatment is not timely, bacterial infection and suppuration in the wound will bring certain difficulties to the treatment. In severe cases, the wound tissue slowly necrosis, and finally formed a thick black scab. It takes several months to heal after scabbing, leaving scars. Never judge the severity of burns by the intensity of pain, so as not to delay treatment. Liu Baoding No.5 Hospital Burn Plastic Surgery Department
