When a finger is scalded, local symptoms such as swelling, redness, heat, and pain—an inflammatory response—will occur. The patient will experience significant pain and a burning sensation. Under these circumstances, it is essential to clean the wound promptly to prevent infection. If there is broken skin, it needs to be disinfected with hydrogen peroxide, then rinsed with saline solution, followed by an application of iodine. It is important to keep the skin at the broken site dry and avoid contact with water and contaminants. With such treatment, the broken skin typically forms a scab within about a week. After another week, the skin in the affected area will heal and regenerate.
