Moreover, uncontrolled neuropathic pain is a significant risk factor for suicide. [22] Certain classes of neuropathic pain may cause serious adverse effects necessitating hospital admission, for instance trigeminal neuralgia can present as a severe crisis where the patient may have difficulty talking, eating and drinking. [23]
Peripheral neuropathy may be classified according to the number and distribution of nerves affected (mononeuropathy, mononeuritis multiplex, or polyneuropathy), the type of nerve fiber predominantly affected (motor, sensory, autonomic), or the process affecting the nerves; e.g., inflammation (), compression (compression neuropathy), chemotherapy (chemotherapy-induced peripheral neuropathy).
Central pain syndrome, also known as central neuropathic pain, [1] is a neurological condition consisting of constant moderate to severe pain due to damage to the central nervous system (CNS) which causes a sensitization of the pain system. [2] [3] The extent of pain and the areas affected are related to the cause of the injury. [4]
In Seddon's Classification, nerve injury is described as either neurapraxia, axonotmesis, or neurotmesis. Following trauma to the nerve, a short onset of afferent impulses, termed "injury discharge", occurs. This occurrence lasts only minutes, but has been linked to the onset of neuropathic pain. [4]
Anterior cutaneous nerve entrapment syndrome (ACNES) is a nerve entrapment condition that causes chronic pain of the abdominal wall. [1] It occurs when nerve endings of the lower thoracic intercostal nerves (7–12) are 'entrapped' in abdominal muscles, causing a severe localized nerve (neuropathic) pain that is usually experienced at the front of the abdomen.
Neuropathic pain is caused by damage to the somatosensory nervous system. Signs and symptoms of neuropathic pain include allodynia (pain caused by non-painful stimuli), hyperalgesia (an increase in pain perception due to painful stimuli), and paresthesia (abnormal sensations such as needle bites, tingling, itching, and decreased or loss of ...
