Pain Journals

We feel pain when specific nerves called nociceptors detect the tissue damage and transmit the information about the damage through the spinal cord to the brain.

EX: Touching a hot surface will send a message through a reflex arc in the spinal cord and cause an immediate contraction of the muscles. This contraction will pull the hand away from the hot surface, limiting further damage.

This reflex occurs so fast that the message has not even reached the brain. However, the pain message does continue to the brain. Once it arrives, it will cause an individual to feel an unpleasant sensation pain. Acute pain can last a moment; rarely does it become chronic pain. Chronic pain persists for long periods. It is resistant to most medical treatments and cause severe problems.
