Meat Loaf has revealed he is suffering with a back injury that "hurts like hell".
The Bat Out Of Hell singer said he has a pinched nerve and that standing up is extremely painful.
Speaking to BBC Radio 5 live's Colin Paterson and Sam Walker, he said: "It doesn't hurt when I'm sitting but when I stand up it's like I'm in Norman Bates' movie, Psycho.
"In it I'm being stabbed by Norman Bates.
"It hurts like hell."
He added: "We're going to see doctors in a couple of weeks."
The 68-year-old sparked fears for his health in June, when he collapsed on stage during a concert in Canada.
He said: "Well that had nothing to do with the pinched nerve.
"It was hydration, dehydration - that was all it was."
