Miley Cyrus -- You've Got Laryngitis!

Wanna see the inside of Miley Cyrus' jacked up throat?? Well, look no further ...

The singer was leaving a medical building in Beverly Hills yesterday ... holding up a medical report which shows she's come down with a case of laryngitis!!!

The doc even includes some images of the inside of her throat ... her inflamed, dilated throat.

Don't worry, it's not bad ... she probably just needs a little rest and some fluids and she'll be good as new in no time (note: we're not exactly doctors).

In the meantime, her new music video sure makes US feel better!
