Amy Schumer revealed her son, Gene, was hospitalized with RSV.

Amy Schumer experienced the “hardest week of” her life as her son, Gene, was “rushed to [the] ER” and hospitalized for RSV while she prepared for her “Saturday Night Live” hosting gig.

“Shout out to all the parents going though this right now,” the comedian wrote via Instagram Sunday, referencing the country’s recent RSV surge.

“I got to be with him the whole day at the hospital and the beautiful humans at [‘SNL’] couldn’t have been more supportive,” the actress, 41, continued, noting that her and Chris Fischer’s 3-year-old is “home and better.”

In addition to thanking “the doctors and nurses who helped us,” Schumer concluded with gratitude for the NBC show.

“The reason this show is so fun to do isn’t actually the performance or the show itself. It’s getting to spend time with the people there,” the “Trainwreck” star gushed. “The cast and the writers of course but the people who are behind the scenes making it run smooth are my favorite. The crew!”

Jessica Seinfeld praised Schumer in the comments, writing that she was “blown away” by the “Inside Amy Schumer” star’s balance as a working mom.

The health scare happened amid Schumer’s "Saturday Night Live" hosting gig.

“Proudest of you on Thursday than I have ever been,” Jerry Seinfeld’s wife wrote. “Treating every nurse and doctor with warmth and appreciation whilst you were melting from fear and stress.

“You made the obvious choice to stay with Gene over going to ‘SNL’ rehearsal that day, and you still managed to absolutely kill it last night,” Jessica, 51, concluded.

The little one, whom Schumer shares with Chris Fischer, is now doing "better."

Actress Krysten Ritter called Schumer a “queen,” while “One Tree Hill” alum Sophia Bush wrote, “So glad the little guy is alright, and that your people held you through it.”

Schumer, who gave birth to her baby boy in 2019, previously hosted “SNL” in October 2015 and May 2018.

The Emmy winner is currently on a 65-date comedy tour, telling People in October that it is “brutal” being away from Gene.

“I just want to be with him as much as I can,” Schumer said last month. “It’s a painful thing.”
