"For all who have been trying to contact me the last few days this is where I've been," he captioned a pic taken straight from his hospital bed. "And I will be in the Hospital through Christmas. All good though, Doctors say I will be back to normal before the New Year. #LupusSucks #ncredible #warrior."
Unfortunately, this isn't the first time Cannon, who revealed he was diagnosed with the autoimmune disease in March 2012, has had to deal with medical issues during the holidays. The 36-year-old comedian first experienced kidney problems in December 2011 when he was vacationing in Aspen, Colorado, with his family.
"Currently being transferred to a hospital in LA," Cannon tweeted at the time. "Thank you all for all your love, prayers and concern. You know me… I will be a'ight."
ET caught up with Cannon earlier this month at the Critics' Choice Awards in Los Angeles, where he couldn't stop gushing about reuniting with his ex-wife, Mariah Carey, and their 5-year-old twins, Monroe and Moroccan, for the holidays.
"All fun, all love, you know what it is!" he said. "Holidays are mainly for kids anyway, when you think about it, and once you go from kids, it's all about family and love and that's what we're trying to spread."
