After experiencing severe pain in her right arm on February 1, Moon Geun Young visited the hospital, and was diagnosed with compartment syndrome. The condition is caused by pressure buildup from internal bleeding or swelling of tissues, decreasing blood flow and depriving muscles and nerves of needed nourishment.

The surgery went successfully, and upon doctor's orders to rest, Moon Geun Young has asked that scheduled performances of her play 'Romeo and Juliet' in Daejun be cancelled from February 4-5. Her label has announced that the actress will need to receive additional surgery in 2 to 3 days. As a result, 'Romeo and Juliet's upcoming performances scheduled later this month may also be cancelled, depending on Moon Geun Young's progress. 

Please get well soon, Moon Geun Young.
