Country music singer Alan Jackson has revealed that he has been suffering from Charcot-Marie-Tooth disease for years in secret.

The hereditary disorder damages nerves in the arms and legs.

“There’s no cure for it, but it’s been affecting me for years,” Jackson said. “And it’s getting more and more obvious. And I know I’m stumbling around on stage. And now I’m having a little trouble balancing, even in front of the microphone, and so I just feel very uncomfortable.”

The disease is not deadly and the singer said he is going to do his best to work through the pain.

“I’m not saying I won’t be able to tour,” Jackson said. “I’ll try to do as much as I can.”

Jackson was born in Georgia on Oct. 17, 1958, and moved to Nashville, Tennessee to pursue a country music career. His first album Here in the Real World was a breakout success, cementing his place in the country music industry.
