Final answer:
The term meaning pain in a nerve or nerves is 'neuralgia,' which includes conditions like sciatica. Neuropathic pain arises from nerve damage and is different from inflammatory pain which is due to tissue injury.
Step-by-step explanation:
The term meaning pain in a nerve or nerves is neuralgia. This type of pain can occur when nerves become inflamed or compressed. An example of this is sciatica, which is a painful condition resulting from inflammation or compression of the sciatic nerve or any of the spinal nerves that contribute to it. Neuropathic pain is pain that results from damage to neurons of either the peripheral or central nervous system, leading to exaggerated pain signals being sent to the brain.
Pain can also be classified as inflammatory pain, which signals tissue damage often resulting from injury. Our sense of touch depends on sensory neurons which transmit information regarding pain, pressure, or temperature from receptors in the body to the central nervous system. The sensitivity to pain varies depending on the density of sensory neurons in different parts of the body.
