Anal sphincter tone was normal.

Examination of his upper limbs, cranial nerves and cerebellum were clinically normal. He was investigated in a medical unit where the diagnosis of transverse myelitis was made based on his clinical presentation and MRI findings which demonstrated transverse myelitis
involving 4th to 7th segment of spinal cord. He was referred to the neurology team who started him on IV methylprednisolone pulse therapy, physiotherapy and referred for rehabilitation after starting on oral prednisolone 1mg/kg.
