What is referred pain?
Pain referral has a neural basis. Specific pathways and neural connections in the brain are thought to lead to the possibility of pain referral.
One group of nerve fibres conduct information about touch and another group conduct information about tissue damage or noxious stimulation via different sensory nerves. Many sensory fibres from different parts of the different area can terminate on the same set of second order neurons. The second order neurones are part of the pathway that sends sensory information to higher centres for perception. However, since there is so much convergence of sensory information from different body parts onto the same second order neurones, these second order neurones may provide ambiguous information as to the exact location of the noxious stimulus. This neural mechanism is thought to be one way whereby the higher centres of the brain can become "confused" as to the exact location of the noxious stimulus.
Another explanation of pain referral is the activating of silent or latent synaptic connections. When there is prolonged and/or intense noxious stimulation, some of these ineffective synapses may become effective connections. The information is transmitted from other parts unrelated to the source of the pain. The brain therefore can become confused as to the correct location of the pain.
There is a simple diagnostic test that can be done to help distinguish referred pain to a tooth. Clinicians can use a diagnostic local anaesthetic to produce a neural inactivation at the site where the patient complains of the pain, e.g. a tooth. If the pain being felt in the tooth is referred pain, then the pain should persist despite the local anaesthetic. Locating the origin of pain is a key step for further treatment.
