Loss of function means you do not have normal
movement with your best effort despite the pain. Sometimes it is hard to tell
whether there is a true loss of function, because you may not want to move the
injured area if movement causes pain.
Most cuts, scrapes, bites, or puncture wounds do
not injure underlying nerves, tendons, ligaments, bones, or joints. It is
common to have burning, tingling, or numbness around the
wound immediately after the injury. This is not a
Prolonged or intense exposure to hot temperatures can cause heat-related illnesses, such as heat exhaustion, heat cramps, and heat stroke (also known as sun stroke). As your body works to cool itself under extreme or prolonged heat, blood rushes to the surface of your skin. As a result, less blood reaches your brain, muscles, and other organs. This can interfere with both your physical strength and your mental capacity, leading, in some cases, to serious danger.

Sometimes a wound will
damage underlying structures. You may not be able to move the injured area, or it may feel numb. This is more serious when the loss of function is not caused by
pain or your symptoms spread beyond the local area of the
injury. Symptoms of damage to
underlying tissues may include:
Loss of feeling
(sensation), which may occur with a nerve injury.

Abnormal movement or loss of function of a joint,
which may occur with a ligament injury or a broken bone.
and inability to move, which may occur with a joint injury.

A deep wound close to or on the hands or feet
can be serious because nerves, tendons, or ligaments are closer to the surface
of the skin. Deep cuts near joints may damage the joint and increase the chance
of an infection in the joint. Crush injuries can cause severe swelling, which
may put pressure on nerves, tendons, and blood vessels.
Permanent disability may result if an injury to a nerve, tendon,
ligament, or joint is not quickly detected and repaired.
