Presentation of severe pain syndromes prior to onset of motor weakness is an uncommon but documented finding in patients with Guillain-Barré syndrome (GBS). Sciatica in GBS is a difficult diagnosis when patients present with acute radiculopathy caused by herniated disc or spondylolysis. A middle-aged woman was admitted for severe low back pain, symptomatic hyponatraemia, vomiting and constipation. On further investigation, she was diagnosed with radiculopathy, and appropriate treatment was initiated. Brief symptomatic improvement was followed by new-onset weakness in lower limbs, which progressed to involve upper limbs and right extraocular muscles. With progressive, ascending, new-onset motor and sensory deficits and laboratory evidence of demyelination by Nerve Conduction Study, a diagnosis of variant GBS was made. She was treated with intravenous immunoglobulin 2 g/kg over 5 days. The presentation of severe low back pain that was masking an existing aetiology and possible dysautonomia and the unilateral right extraocular muscles instead of bilateral make our case unique and rare.
