Pain is unique to each of us. Our perceptions of pain result from a series of messages that alert us to injury, warning us of danger or to withdraw from danger! How we interpret these messages depends on many different factors.
Pain involves a complex series of messages that travel along the nerves connecting the site of injury and various parts of the nervous system.
Stimulation of certain mechanisms within the nervous system leads to transmission of messages from the injured part, along the nerves, passing from one neuron to the other.
At the junction of the nerves, a number of chemical reactions take place, to allow messages to be transmitted,
Messages are transmitted from the periphery to the spinal cord, and to various parts of the brain, where we interpret the sensations.
