Stephen Fry has said he sometimes thought of his chronic pain "as a friend" as he tried to manage his condition after an accident.
The actor was injured in a 6ft (1.8m) fall from a stage at London's O2 Arena last year, which left him needing constant physiotherapy.
He told Radio 4's Today programme that living with chronic pain "makes you afraid of basic movements".
The 67-year-old said: "You almost call it a friend and say 'It's OK, I know why you're there' and you're not a failure on the part of evolution, or God, or whatever you want to call nature."
