., on Wednesday, two days after being admitted for intestinal pain.
Vonn's publicist Lewis Kay said it's unclear when the four-time overall World Cup champion will return to skiing.
"She is resting comfortably at home," Kay wrote in an email. "Doctors are still working to determine what specifically was the cause of her illness, but thankfully she has responded well to their treatment."
On Tuesday, Kay said Vonn was "awaiting results from diagnostic testing for severe intestinal pain," but his latest statement did not specify the reason for the hospitalization.
Her next scheduled races are the giant slalom and slalom in Aspen on Nov. 24-25, followed by speed events in Lake Louise, Alberta — her most successful stop on the circuit.
Vonn's ski technician, Heinz Haemmerle, told The Associated Press on Tuesday that Vonn has visited the hospital two or three times in the past week. Haemmerle said Vonn told him she "has pain all over her body and that her bones are hurting."
He declined to offer an update when contacted by the AP on Wednesday.
Haemmerle, who prepares Vonn's Head skis, said Vonn hasn't trained since going out in the second run of the season-opening giant slalom on Oct. 27 in Soelden, Austria.
Vonn recently requested to compete in a men's downhill race, only to be rejected by the International Ski Federation. She was hoping to enter the men's race Nov. 24 at Lake Louise, Alberta. Had she been allowed to compete against the men, Vonn would have missed the two women's races in Aspen.
Last weekend, Vonn skipped a slalom in Levi, Finland, which Haemmerle said was planned to allow more training for the Aspen races. It's the only women's World Cup event in the United States.
