10 celebs who were diagnosed with painful diseases (With Pictures)

8. Nick Cannon — Lupus

Nick Cannon had to quit his radio show because it was taking up so much time of his day, preventing him from getting any sleep. On top of that, the TV host suffers from lupus and acute kidney failure — this pretty much means that pushing yourself to the boundaries of no sleep and consistent work is sure to land you back in the hospital. Cannon has been hospitalized on multiple occasions in 2014, having complained of painful stomach aches because of his disease, hence why he has chosen to do less work and focus on more resting time.
