Olympic gold medalist McKayla Maroney went into surgery on March 25 to correct a month-long painful bottle with kidney stones.
She dubbed the surgery a success on social media.
"I think my surgery was a success. On to recovery," she wrote on her Instagram Stories from the hospital bed.
McKayla, 25, acknowledged she was nervous prior to going under the knife and even cried.
"Not [going to] lie I really didn't want surgery," she told her 1.3 million followers. "I was pretty sad, and scared of the bad possible outcomes, and the pain. I'm happy it's over, but it's gonna be at least a week more of pain w this stint then I'll be good I think."
McKayla spoke of her heath issues last month after rushing to the emergency room for "severe pain" in her back and stomach.
"Had to come to the ER at 3am because pain kept getting worse, and I couldnt' stop throwing up," she wrote on Instagram on Feb. 25. "Just got my CT Scan back. I have a few kidney stones."
A week later, she indicated that she might need surgery and called the medical episode a "wildcard" she didn't foresee.
McKayla was a member of the 2012 gold medal-winning United States Olympics team that was dubbed the "Fierce Five." She also won an individual silver medal on the vault. At the ceremony during which she received her silver medal, McKayla seemed less than thrilled with the results — she memorably appeared unimpressed while pictured on the podium, creating one of the most viral moments of the year. She later recreated her "not impressed" look with then-President Barack Obama during a visit to the White House.
Since retiring from competitive gymnastics, McKayla has acted on several TV shows, including "Hart of Dixie" and "Bones." She's also played herself on several other programs.
