Neuropathic pain and neuromodulation techniques

Abstract

Neuropathic pain is a common chronic intractable pain syndrome in clinical setting. It arises as a consequence of a lesion or disease affecting the somatosensory system /INS;[1] and may be associated with abnormal sensations called dysesthesia, pain produced by normally non-painful stimuli called allodynia and spontaneous pain. The mechanism of neuropathic pain remains /INS;unclear so far, and the management of patients with chronic neuropathic pain is challenging /INS;[2–/INS;6]. In this paper, I will discuss in brief the etiology, physiopathology and clinical management of neuropathic pain.
