After getting burned and if there is no burn ointment at hand, you should first remove the clothes around the burn, and then rinse or soak the wound in cold water for more than half an hour, and then apply vegetable oil to the wound.

If there is noticeable redness, swelling, and pain, as well as blisters of various sizes, you can use a sterilized needle to puncture the blisters from the bottom, and squeeze out the blister fluid from top to bottom, but do not tear off the blister skin. Then disinfect with iodine and wrap the wound with a clean cloth, and promptly go to the hospital for further treatment. The patient should avoid spicy and irritating foods to reduce congestion and swelling at the burned area, thereby reducing local pain and itching.
