Michael Jackson apparently bruised his ribs during a vigorous dance workout in his bedroom, causing the chest pains that put him in the hospital, his doctor says.
Tests of Jackson's heart and lungs revealed no abnormalities, Dr. Mark Zatzkis, a cardiologist, said Wednesday in a statement. The singer should be released from St. Johns Hospital and Health Center in Santa Monica, Calif., this week, said Jackson spokesman Bob Jones.Jackson had complained of chest pains when he went to the hospital Sunday. He suffered costochondritis, or inflammation of the cartilage in the front part of the ribs, Zatzkis said.
Late Wednesday, Jackson's brothers Jackie, Marlon and Randy arrived at the hospital to visit him.
