Singer Wheesung has undergone surgery for his back problems while serving his military term.

A representative of Wheesung's agency revealed, "Wheesung has gotten a surgery for herniated disc on July 11. The surgery went well and he is currently recovering in the hospital."

They also said, "Wheesung has been suffering from a bad shoulder and disc problems even before his enlistment in the army, but with pain getting worse, decided to take a temporary leave and go under surgery."

A representative of the hospital told the press, "The doctor said that Wheesung might not be able to finish his military term and recommended his discharge. However, Wheesung is determined to return and serve out the remainder of his military service and said that he will be returning as soon as he is fully recovered."

Wheesung's shoulder and back definitely need time to heal so he will be resting for at least 10 days and he is scheduled to be discharged from the hospital on July 13.
