Neurogenic pain

Neurogenic pain is a type of pain that can be defined as pain due to damage to the peripheral or central nervous system and is not explained by nociceptor irritation. Neurogenic pain has many clinical forms. These include some lesions of the peripheral nervous system, such as postherpetic neuralgia, diabetic neuropathy, incomplete injury of the peripheral nerve, especially the median and ulnar (reflex sympathetic dystrophy), detachment of branches of the brachial plexus. Neurogenic pain due to central nervous system damage is usually due to a cerebrovascular accident - this is known by the classic name of "thalamic syndrome", although studies (Bowsher et al., 1984) show that in most cases lesions are located in areas other than the thalamus.
