Most bites do not injure underlying nerves, tendons, ligaments,
bones, or joints. It is common to have burning, tingling, or numbness around
the bite immediately after the injury. This is not a concern.
Sometimes it's hard to tell if there is a true loss of function
because you may not want to move the injured area if movement causes pain. Loss
of function is present when your best effort does not result in normal
movement.
Occasionally a bite will injure underlying structures, causing a loss
of function or numbness. The seriousness increases when the loss of function is
not caused by pain or when your symptoms spread beyond the local area of the
bite. Symptoms of injury to underlying tissues may include:
- Inability to move and loss of feeling
(sensation), which may occur with a nerve injury.
- Inability to
move, which may occur with an injury to a nerve or
tendon.
- Abnormal movement or loss of function of a
joint, which may occur with a ligament injury.
- Swelling and
inability to move, which may occur with a joint injury.
- Pain,
abnormal movement, or loss of function, which may occur with a bone
injury.
A deep bite 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 bites
near joints may damage the joint and increase the chance for an infection in
the joint. Crushing bite 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.
