If the scald area is small, you can apply some disinfectant ointment, such as iodine or erythromycin ointment, after cleaning, and cover the wound with sterile dressing. This can prevent bacterial infection and play a protective role.
If the burn area is large or serious, it is recommended to seek medical advice as soon as possible. In the process of waiting for medical treatment, you can wrap the injured part with clean wet gauze and raise the affected limb to reduce the blood flow to the injured part. Avoid herpes, scratching, rubbing and other operations to avoid aggravating the injury.
When dealing with hand burns, you should keep calm, take correct first aid measures and seek medical treatment as appropriate. Remember, burn wounds should be kept clean and changed regularly. For pain and discomfort, you can take some painkillers orally, but you should also follow the doctor's advice.
I hope these suggestions are helpful to you. I wish you a speedy recovery!
