The 'DIY SOS' star suffered a nasty injury just days before he went to the jungle, and he decided to keep it quiet from viewers.

Appearing on ITV's 'Lorraine', he said: "I had an injury before I went. About five days before I went in I basically compressed a couple of vertebrae in my neck and tore two ligaments in my shoulder.

"So I was in an MRI machine just two days before I went out and then when I got to Australia I had four cortisone injections in my shoulder. [The show's medic] Doctor Bob would come and check up on me."

Nick, 56, explained he decided to keep it a secret because he wanted to avoid getting the "sympathy vote".

He added: "I didn't want the sympathy vote - just do it and get on with it and get through and out the other side.

"That's why I'd sit in that freezing cold pool because it would freeze my shoulder. I hate cold water as well. It'd go numb and I'd get about an hour's worth of relief off of it."

Meanwhile, Nick - who will be auctioning off his now infamous red 'budgie smugglers' for charity - also opened up about calling the in the medical team for campmate and eventual winner Harry Redknapp.

He said: "That morning he stood up - a lot of people getting dizzy through lack of food and things - he stood up and then was a little giddy on his feet. He said, 'That was a bit odd'.

"Then we went down and he did it again in the shower. I noticed his lip was dropped on one side. Now, my father died of a stroke. I immediately was like I want to get the medics in here straight away. He's almost 82, I want to make sure he's ok.

"It turned out what it was, he was a little low on body sugars, which was making him dizzy. Bit dehydrated, which made him dizzy. Actually, he'd got a bite on his lip from one of the trials, which made his lip swell, which made him look lower on one side - enough signs for me to go [and get help]."
