Recently, many celebrities have been going to the hospital for various treatments. Joining this unfortunate list is singer Brian Joo who recently wrote on Twitter: "Just got out of the hospital, cos I have severe enteritis. Hate being sick, esp. when I need to work. Right now, I left the hospital after being treated with Ringer's solution for two hours~ they say the enteritis is severe TT TT" Further tweets reveal that he is having a hard time rehearsing due to his current condition, the most recent tweet stated: "Finally going home after practicing in my sick condition... Today was really hard... And I'm a bit sad that only I know about the pain. Finally, done for the day. Man, I can barely move now. No one knows my pain." Hopefully, he is getting some rest now so that he can quickly regain his strength! Source: Twitter Tip: namelessloverxx
