Scalded epidermis is fine but fiery pain appears, which is caused by the skin being stimulated by high temperature substances without flame, such as scalding caused by boiling water, hot oil, high temperature steam and other substances. If the epidermis is fine, it is possible that the exudation has not formed within a short period of time, or because the degree of the burn is a first-degree burn, so it only shows local dryness and the surface of the skin is fine to the naked eye. The accompanying hot and painful sensation is usually due to the high temperature scald, because the high temperature material carries a lot of heat quickly conduct to the epidermal cells, causing cell damage, which can release inflammatory factors, causing local pain. In addition, because there are more peripheral nerves in the epidermis, it will be extra sensitive to pain, causing a burning sensation. Although the epidermis seems to be fine at this time, there may be damage to the subepidermal structures, so it is recommended that patients rinse with cold water immediately after scalding to make the heat under the epidermis subside as soon as possible, so as to prevent the local heat from continuing and further damaging the skin and subcutaneous tissues after scalding, and also to reduce the temperature and pain, reduce exudation and swelling, so as to prevent the residual temperature from damaging the cells and leading to blister formation to a certain extent, and prevent the scalding that seems to be fine at this time from The burns that seem to be fine at this point progress to moderate burns. After rinsing with cold water, you can apply topical Kywanghong ointment, burn cream, etc. to help relieve the symptoms. However, care needs to be taken to avoid rinsing with ice water or direct contact with ice to avoid frostbite of the skin and cause re-injury. Generally speaking, you can recover in about a week.
