Who's the Star Trek character?Man Bleeds Green Blood, Shocks Surgeons
A man undergoing leg surgery in Canada has stunned doctors after he bled a green-black blood that has been likened to that of Star Trek character, Dr Spock. Vulcans have green blood, according to the Star Trek story.
The patient had been taking high doses of migraine medication, which caused a condition called sulfhaemoglobinaemia. Sulfhaemoglobinaemia occurs when sulfur enters into the red blood cells' haemoglobin.
The man had to undergo the surgery on his legs after falling asleep in the sitting position.
What prompted the surgery? Um... EEK?
