A woman suffering from a rare form of tinnitus has been stuck with the song "How Much Is That Doggy In The Window" for the last three years - and there's no sign it will ever stop.
The condition called "musical hallucination" leaves a person with the same song stuck in their head on a loop all day. "It's like having a radio that you just can't turn off," says Susan Root, a pensioner from England.
Susan says the song in her head is sometimes so loud that she can't hear her husband speaking.
"I began hearing tunes in my ears three years ago and it just has not stopped since. It's especially bad at night time and I have terrible trouble getting to sleep - it drives me to breaking-point at times."
The Sun reports that doctors have been unable to help cure her problem, though she has found ambient CDs of whale and bird songs helpful.
She added: "They have given me a hearing aid which they had hoped would fix my hearing problems and therefore stop the music but it just hasn't worked. I had special therapy too but they've now told me there is nothing more they can do. I've come to accept that I'm probably going to be stuck with this hellish condition for the rest of my life."
