Meralgia paresthetica characterised by pain, tingling and numbness in lateral aspect of thigh. A 48 year-old male with 2 years history of left lateral thigh paresthesias and burning pain consistent with meralgia paresthetica was referred to our clinic after failing trials of physical therapy, nonsteroidal anti-inflammatories and neuropathic medications. We performed lateral femoral cutaneous nerve block with corticosteroid, after that patient had good relief for 2 months; however, block provided only temporary relief and patient again started feeling same pain. As this pain was limiting the patient's ability to perform his functions as truck driver, we planned to perform a pulsed radiofrequency treatment of the lateral femoral cutaneous nerve left side under ultrasound guidance. After locating the lateral femoral cutaneous nerve with ultrasound and reproducing the patient's dysesthesia with stimulation, pulsed radiofrequency treatment was performed at 42°C for 120 seconds. The needle was then rotated 180° and an additional cycle of pulsed radiofrequency treatment was performed followed by injection of 0.125 % bupivacaine with 20 mg triamcinolone. At 2 and 4 month follow-up visits, the patient reported excellent pain relief with activity and improved ability to perform his duties. We have also described various aetiologies for meralgia paresthetica and multiple modalities available for the treatment of meralgia paresthetica.

Leukocytoclastic vasculitis (LCV) is a small-vessel vasculitis with a reported incidence rate of 30 cases per million persons per year. It usually presents as a palpable purpuric skin rash on legs, though any part of the body can be affected. LCV rash may have an associated burning sensation or pain and in some cases may involve internal organs. In some cases, LCV rash may present as nodules, recurrent ulcerations or asymptomatic lesions. The diagnosis of LCV is usually made on skin biopsy. Etiological triggers may not be identified in as many as half of the cases. Treatment is usually conservative and includes identification and removal or treatment of the etiological trigger except in cases with internal organ involvement where systemic steroids and immunosuppressant may be necessary. In this article we present a case of Amoxicillin and Clavulanate potassium associated LCV that improved with discontinuation of the offending agent and treatment with systemic corticosteroids.
