Olympic gold medalist Lindsey Vonn was released from a Colorado hospital on Wednesday, after spending two nights there due to “severe intestinal pain” that has been plaguing her for the past two weeks, NBC reported.

Lewis Kay, a spokesman for the 28-year-old reigning World Cup champion, wrote in an e-mail on Tuesday that Vonn was “awaiting results from diagnostic testing for severe intestinal pain,” the Associated Press reported

On Wednesday, he announced in another e-mail, "Lindsey is feeling much better today and has been released from the hospital. She is resting comfortably at home. Doctors are still working to determine what specifically was the cause of her illness but thankfully she has responded well to their treatment. We do not know when she will be able to return to the mountain and will update as her health improves."

According to Vonn’s ski technician, Heinz Haemmerle, the alpine skiier hadn't undergone any training since competing in the woman’s Giant Slalom event for the World Cup Opening in Soelden, Austria at the end of October.

Vonn, the defending champion, was in 12th place at the end of her first run, but soon after embarking on her second, she caught her arm on a gate and crashed. “That was definitely not the plan,” Vonn said, on the United States’ Ski Team’s website. “In the first run, I felt like I skied solid, but didn’t risk enough. I was a little bit too conservative on the pitch... I just didn’t execute the way I was hoping to today.”

“I have to fight harder than I did today – lesson learned. I’m happy and I’m just going to try and get ready for the next races,” she added in an interview after the event.

After leaving Austria, Vonn reportedly attended the Snow Ball in New York before heading back to Vail, Colo. But shortly after returning home, she seemed to come down with a mystery illness.

“She told me she feels bad and has pain all over her body and that her bones are hurting. ... She’s been (to the hospital) two or three times. This is the first time she’s stayed overnight,” Haemmerle told the Associated Press in a telephone interview. “The coaches also don’t know. First they told me we would train again Monday, then Wednesday, now the end of the week.”

“There’s been no news, so we’re kind of worried,” added Rainer Salzgeber, Head racing director, in a phone interview Tuesday from Austria. “It’s not good.”

Salzberger and Haemmerle both gave corroborating reports that Vonn had not recently suffered from any broken bones or skiing injuries.

Vonn is the most successful U.S. female skier in history, and the most successful American ever in alpine skiing. She is a four-time overall World Cup champion and has had 53 World Cup victories, five world championship medals, and in 2010 she became the first American to win the Olympic gold medal in downhill skiing.
