What is Pain?
When we feel pain it is the body's process of informing us that something is
wrong. To feel pain is important, without this feeling abnormal conditions may
go undetected, creating damage or injury to critical parts of the body.
Although pain is essential in warning our body of trauma or malfunction,
nature may have gone too far in its design. Continued long-term chronic pain
has no useful value apart from its importance in diagnosis. Pain begins when
a coded signal travels to the brain where it is decoded, and analysed. The pain
message travels from the injured area of the body along small diameter nerves
leading to the spinal cord. At this point the message is switched to a different
kind of nerve that travels up the spinal cord to the brain area. The brain then
analyses the pain message, refers it back and the pain is felt.
