A number of different cancer chemotherapy agents such as cisplatin,oxaliplatin,and paclitaxel can lead to nerve damage,thereby giving rise to neuropathic pain states that present with mechanical and cold allodynia[1].Although these pain conditions often resolve after completion of the chemotherapy,a significant portion of patients exhibit longlasting pain that can persist longer than 12 months with a negative impact on the quality of life of affected individuals[1].
