Bernhardt-Roth syndrome (BRS) is a neurological condition characterised by pain, burning or numbness in anterolateral thigh due to entrapment of the lateral femoral cutaneous nerve (LFCN). The possible aetiologies can be mechanical, iatrogenic, neuropathic or idiopathic. After consent for possible publication, we are discussing a case of pain management in a 38-year-old patient with BRS secondary to diabetes. The coherent history, uncontrolled glycaemic status and reduced nerve conduction velocity for LFCN helped reach the diagnosis. Initial treatment with pharmacotherapy, steroid LFCN block and conventional pulsed radiofrequency (PRF) provided moderate temporary pain relief. Extended PRF over 8 min provided significant analgesia without any complications. Physical therapy, adequate glycaemic control and extended PRF provided complete pain relief and improved function over 6 months of follow-up duration. Hence, a cautious multifaceted approach targeting the basic aetiology with extended PRF helped achieve significant analgesia in our refractory case of BRS.
