In fact he had been unwell for a year with malaise and fatigue, significant weight loss, progressive breathlessness and night sweats. Indeed, he had seen his family doctor 9 months previously and was found to be polycythaemic, and had had a total of seven units of blood venesected without clinical improvement. Subsequent detailed questioning elicited a history of postural dizziness and presyncope – particularly after venesection, urinary frequency, impotence, gustatory sweating, and more recently, ascending numbness and dysaesthesia of the hands and feet, poor grip strength and bilateral foot drop.
