Occurs when the nervous system is not functioning correctly.
Neuropathic pain can be described as any change or obstruction to the function of any nerves.

It is reported that the combination of extended chronic pain and insomnia may increase the risk of suicidal ideation in pain patients.

What is Neuropathic Pain reference


Pain that sustains after a peripheral nerve injury is called neuropathic pain, also known as neuralgia. After peripheral injuries, microglial cells surround the synapses between pain fibers and neurons in the dorsal horn of the spinal cord, releasing chemicals that make the dorsal horn neurons hyper-excitable. This leads to neural signaling of pain in the hypothalamus. 

Cases of neuropathic pain can be considered disagreeable examples of neural plasticity since the nervous system (either the spinal cord or the cortex) amplifies its response to the pain signal.
