Conservative talk radio show host Rush Limbaugh said Friday tests showed nothing was wrong with his heart after he was hospitalized with chest pains. Limbaugh, 58, was released from The Queen's Medical Center two days after he was rushed there during a vacation. Doctors said he did not have a heart attack or heart disease.

"The pain was real, and they don't know what caused it," Limbaugh said, adding his best guess was he had a spasm in an artery.
