Neuropathic pain is characterized by unpleasant symptoms such as shooting pain or burning sensation, numbness, altered sensation and sensations that are very difficult to describe.
According to the International Association for the Study of Pain , neuropathic pain is the direct result of an injury or disease affecting the somatosensory system. For the majority of neuropathic pain, there is no effective treatment in time, and some are even refractory to the most powerful analgesics such as morphine or tramadol. Most often, anti-epileptics or anti-depressants are prescribed despite their associated side effects.
According to the STOPNEP epidemiological survey (« Study of the Prevalence of Neuropathic Pain »), carried out in France (source: Livre Blanc de la Douleur), the prevalence of neuropathic pain in France represents 7% of the population of which 5% have moderate to severe pain.
