High proportions of patients have reported neuropathic pain after traumatic nerve injury. [1][2][3] A lesion or disorder of the somatosensory nervous system may result in neuropathic pain 4 which can cause a higher prevalence of sleep disturbances, 5 anxiety, 6 and depression 7 in patients. The prevalence of neuropathic pain has been estimated at around 6.9%-10%. 8 Risk factors for neuropathic pain include demographic, psychological, social/lifestyle, and genetic factors. 9 Post-traumatic peripheral neuropathic pain (PTNP) is defined as chronic neuropathic pain due to damage to peripheral nerves. 10 Some therapeutic interventions have been suggested as treatments for PTNP such as transcutaneous magnetic stimulation, 11 gabapentin, 12 and pregabalin. 13 The potential treatment of pregabalin has been shown in both central and peripheral neuropathic pain. 1,14,15 Some studies showed its efficacy as off-label uses for other conditions such as generalized anxiety disorder, 16 restless legs syndrome, 17 bipolar disorder, 18 and insomnia. 19 Most meta-analyses have been undertaken on the therapeutic value of pregabalin in patients with diabetic peripheral neuropathy (DPN), 20,21 post-herpetic neuralgia (PHN), 22,23 fibromyalgia, 24 and spinal cord injury
