Nathan recently told E! News that he was totally devastated when he found out he had to have surgery and that he even had a panic attack before he went under the knife.
Aww, poor guy!
Don't worry, everything is fine with him now and he actually just performed with the band for the first time since his surgery last week! Read about that here!
