Violin virtuoso Nicola Benedetti has had to pull out of her US tour because of a painful back injury.
She had to cancel three concerts last week because of the mystery ailment and last month she was unfit to perform two UK shows.
Experts believe her aggressive playing style may have strained her back.
Nicola, 20, of West Kilbride, Ayrshire, said: "The doctors haven't been able to say exactly what's causing it but I'm sure all the travelling and playing all the time has something to do with it."
She is due to play in Glasgow, Edinburgh and Aberdeen next month.
