HONG KONG: Popular Canto-pop singer Joey Yung has been diagnosed with early-onset knee joint degeneration.

Her doctor said Yung's hectic schedule and chronic lack of rest had brought about this condition, and if she continues like this, she might not be able to jog in future.

"It hurts whenever I walk, especailly on slopes," she said. "I always go all out in everything I do and may have neglected my health for too long."

Yung, 29, said she was shocked when she heard the news and will have to undergo physiotherapy for her condition.

For now, she is determined to keep on performing and refuses to give up her heels.

"I'll probably wear shorter heels now, but when I really need to look my best, I'll wear taller heels, the taller the better!"

The effervescent singer performed in eight-inch (20 centimetres) heels at her latest concert.
