In the case of minor burns, skin injury symptoms do not need to be treated by a doctor. However, in some cases, a doctor is needed to treat your skin injury. For instance, if you develop a keloid-an overgrown scar-you will need your doctor's help to remove it. While they generally do not cause medical problems, keloids can be aesthetically unpleasing and can, occasionally, limit mobility.
If you have a severe burn, you will also need to see a doctor for treatment. In fact, serious burns, large burns, or burns on sensitive areas of your body should be treated by emergency personnel.
