Lady Gaga had a tough time in the Mile-High City!

The 28-year-old singer was hospitalized for altitude sickness Wednesday night after her concert at Denver's Pepsi Center. She Instagrammed a selfie from the hospital showing her in full makeup, fake lashes and...an oxygen mask! "Altitude Sickness is no Joke!" she wrote. "#hitThatHospiitalS--t #artRaveDenver many true ravers crowd tonight."

Poor thing! Mother Monster isn't the first star to suffer from altitude sickness. In February 2013, Carrie Underwood required some oxygen mid-performance in Broomfield, Colo. She Instagrammed a selfie while wearing her mask, explaining, "In high altitudes, they put oxygen in my dressing room under the stage! This is me before the encore..."

These ladies are troupers! Altitude sickness, which can be serious, often causes throbbing headaches, dizziness, nausea, weakness, sleeplessness and other flu-like symptoms, according to WebMD. It can also be quite serious if not treated, so it's a good thing Gaga and Carrie sought medical assistance when they weren't quite feeling like themselves in those higher elevations. 

Both ladies are lucky, too, that they have hunky fellas, precious pups and loving fans eager to help bring them back to health!
