Features of severe burns:

1. Severe pain: Severe burns can cause intense pain that may be difficult to manage with over-the-counter pain medications.

2. Blistering: Severe burns often result in the formation of blisters on the skin, which can be painful and increase the risk of infection.

3. Redness and swelling: The affected area of skin may become red, swollen, and inflamed following a severe burn injury.

4. Peeling skin: As the burn heals, the affected skin may begin to peel and slough off, revealing new skin underneath.

5. Scarring: Severe burns can cause permanent scarring and disfigurement, especially if they cover a large area of the body.

6. Difficulty moving: Burns that affect joints or muscles can make it difficult to move or use the affected body part.

7. Infection: Severe burns can increase the risk of infection, as the damaged skin is more susceptible to bacteria and other pathogens.

8. Shock: Severe burns can lead to shock, a life-threatening condition that occurs when the body is unable to get enough oxygen and nutrients to its vital organs.

9. Respiratory problems: Burns to the face or airway can cause difficulty breathing and other respiratory problems.

10. Organ damage: In severe cases, burns can damage internal organs, leading to complications such as kidney failure or sepsis.
