Green, whose real name is Stephen Manderson, said he fell 'face down' after suffering a grand mal seizure while on his own at home.
The London-born performer had to cancel his UK tour that year after fracturing three vertebrae in his neck after suffering the medical episode. He then suffered two further seizures.
"There's one theory - I've run myself into the ground doing way too much, over-stretching myself as per usual and it's finally caught up on me. "Rest, studio, books, and efforts into building what might even be a relationship... A healthy one. Not one based on toxicity. Crazy, I know." Someone suffering from a grand mal will lose consciousness and go stiff, often falling to the floor, in what is known as the tonic stage of the seizure.These type of seizures can be dangerous for those who suffer them, as the initial fall can result in serious injury, while the convulsions can also cause further damage.
