Definition of Pain
“An unpleasant sensory & emotional experience associated with actual or potential tissue damage, or described in terms of such damage.”
Nociceptors
Results from an external stimuli on an uninjured, fully functional nervous system. Temporary pain unless underlying cause is not treated.
Gate Control Theory
Stimulation of small (pain) fibers causes gates to open, stimulation of large (heat, cold, mechanical) fibers causes gates to close.
Somatic Pain
Originates from nociceptors located in skin & musculoskeletal tissues, localized, described as sharp
Visceral Pain
Originates form internal body organs & linings of body cavities, described as dull, deep, aching
Referred Pain
Sensed in a region other than the site of origin
Phantom Pain
pain felt in an amputated limb or body part, recurring, described as shooting, stabbing, squeezing, throbbing, or burning.
Biological Pain Stimuli
Bacteria, viruses
Mechanical Pain Stimuli
Shearing forces, fractures
Thermal Pain Stimuli
Extreme heat (burn) & extreme cold (frostbite)
Electrical Pain Stimuli
Electrical burn, electrical shock
Chemical Pain Stimuli
Cleaning solutions, tobacco smoke, acids/bases, radiation
Nociceptive Pain
results from external stimuli on an uninjured, fully functional nervous system. Temporary pain unless underlying cause not treated
Neurotic Pain
caused by nerve malfunction or injuries resulting from trauma, disease, chemicals, infections, & tumors. Consequent spontaneous pain may be due to damage of either peripheral or central nerves.
