Sheen's publicist has spoken only of the actor suffering from abdominal pain.
According to Sheen's publicist, Stan Rosenfield, Sheen was having severe abdominal pains Thursday and went to the hospital.
Rosenfield said Sheen has had a history of hernia problems and that the unidentified woman who made the early morning 911 call on Sheen's behalf "said he had severe stomach pains and said it was from a hernia condition."
The Los Angeles City Fire Dept. confirmed they responded to a medical call at Sheen's home on the 14000 block of West Aubrey Rd. at 6:30 a.m.
This incident is Sheen's third visit to a hospital in as many months and is the latest chapter in Sheen's wild ways.
Last fall, Sheen was rushed to a New York City hospital after authorities found him naked and disoriented at the Plaza Hotel New York.
A pornography actress later accused the sitcom star of attacking her in that hotel room.
Twice in 2010, Sheen's Mercedes-Benz was allegedly stolen out of his garage and found at the bottom of a ravine near his home.
In 2009, Sheen faced assault charges in Aspen, Colo., after a dispute with his wife, Brooke Mueller.
Wednesday night, Sheen's "Two and a Half Men" co-star Jon Cryer appeared on Conan O'Brien's TV talk show. Cryer talked about how strange things seem to happen to Sheen.
