“I was like, wait, I have been getting steroid injections for my scars,” the Trainwreck actress said on Call Her Daddy. “I had a breast reduction, you know, C-section, whatever.”

Schumer—who shares son Gene, 5, with husband Chris Fischer—confirmed she received her diagnosis not long before she started filming her upcoming Netflix comedy movie, Kinda Pregnant, in March.

“Right before we started rolling was when I learned I had this condition,” she explained, “and that I had something called moon face.”

Schumer said she initially feared the worst. “There are two kinds of Cushing and [with] one of them, you could die,” she recalled. “And so for like, 24 hours, I was like, I’m dead. So I was feeling really down on myself before I started filming this movie.”

However, these days, she is on the mend. “So anyway, I got rid of [it],” she emphasized. “Like, it just has to work itself out.”
