Feeling the Pain Pain is a major defense mechanism: It is actually a very important action of the peripheral nervous system that is essential to our well being. Here is how it works! • It tells us something is wrong with our body that we can’t see otherwise. Example: Abdominal pain; gas, constipation, infection • It helps us avoid dangerous things. Example: We touch a hot fire; we feel pain and pull away with spinal reflex immediately. • It helps us protect damaged body parts. Example: We shield injuries from physical contact (guarding) and limit use of injured muscle/skin to promote healing. The most common categories are: • Thermal - Heat or Cold • Mechanical - Crushing, Tearing, etc. • Chemical - Iodine in a cut, chili powder in the eyes
