The cause of her injury has not been disclosed.
The 72-year old virtuoso experienced similar injuries in the past. In 2005, she began a five-year hiatus in order to heal her left index finger. The injury seemed to subside once she returned to performing for recital tours in 2010.
However, as the years went on, she explained that after recording the Bach Sonatas and Partitas, her injury still sometimes bothered her.
“During the recording, there was a pain in my left hand, which had been injured before, and I had to take pain killers,” Ms. Chung said in 2016. “I am still treating the injury and recovering.”
