She’s a firm believer in the old saying, “The show must go on,” but after her concert in Denver last night (August 6), Lady Gaga sought medical treatment.

It turns out the elevation of the Mile High City got the best of Mother Monster, and she ended up with altitude sickness.

Following the gig, Gaga posted a selfie via Instagram and in the photo she’s wearing an oxygen mask to help combat the effects of Denver’s thinner air.

She captioned the shot, "Altitude Sickness is no Joke! hitThatHospitalS--t #artRaveDenver many true ravers crowd tonight."
