Burns are among the most excruciatingly painful physical injuries.
Even a relatively minor burn can be intensely painful. A burn occurs when the skin, and often other bodily organs, come in contact with heat, radiation, electricity or chemicals for a period long enough to cause damage. Burns can affect many body parts aside from the site of the burn. Nerves, blood vessels, bones, muscles and other areas may be involved when another part of the body is injured. For example, the respiratory system may be hampered or shut down from smoke inhalation and the kidneys and heart may be damaged from fluctuations in the balance of fluids and electrolytes following a burn.
