If you burn your foot with hot water, rinse it under tap water to cool it down and consult an emergency room or burn unit promptly. Keep the scalded area clean, do not apply toothpaste or soy sauce to the scalded area to affect heat dissipation, secondly, you should avoid secondary infection of the wound, follow medical advice, use scalding cream and other medications reasonably, do a good job of changing medication and disinfection care every day, if blisters appear, small blisters do not need to be treated and can often be absorbed on their own. When large blisters have tight skin and feel painful, the herpes can be drained by pumping the herpes, but the walls are not completely removed to protect the wound. If there are systemic symptoms such as fever and dehydration they need prompt anti-inflammatory and rehydration treatment.
