Abstract: Meralgia Paresthetica is a neurological condition characterized by burning pain, numbness and tingling sensation along the distribution of the lateral femoral cutaneous nerve caused by either entrapment or compression. We report a case in 36 years old female patient presented with a history of pain and paresthesias in the right anterolateral aspect of thigh consistent with Meralgia paresthetica. We performed diagnostic block for lateral femoral cutaneous nerve (LFCN) which resulted in 90% pain relief. So based on the diagnostic block results we performed pulsed Radiofrequency ablation (PRF) of LFCN and DRG at L2 & L3 spinal segment level at 42?C for 120 seconds for 2 cycles followed by 40mg depomedrol injection at each site. The patient reported long term pain relief after procedure.
