(CNN) – South Carolina Rep. Joe Wilson was released from the hospital Saturday after being treated five days for an extended fever and "chronic viral-type infection," according to information released by his staff.
Last week, when Wilson's office announced that a series of appearances in his district would be rescheduled, they initially attributed his illness "to his recent possible contraction of Lyme disease."
Speaking to Kevin Cohen's radio show from his Lexington Medical Center hospital room Friday evening, the Republican congressman said, "Initially I thought it was due to a tick bite in the yard – I love working in the yard – but that wasn't it."
What Wilson thought was a tick bite turned out to be a little rash. He said he started feeling ill two weeks ago after spending a lot of time in the sun, first at the Pelion Peanut Party with his grandsons followed by a funeral in Orangeburg.
"I just thought that being in the sun all morning that I'd gotten overheated. But then I realized I had a fever, it's a low grade fever, and then I went to our family doctor," Wilson said on WVOC-560 AM.
Wilson was admitted to the West Columbia hospital last Monday and started undergoing a battery of tests to diagnose the infection that led to the fever.
"I'm learning things that hopefully will be helpful for other people. That is, it is not unusual to not be able to identify what the problem is and that after a period of time it will simply go away," Wilson said.
Wilson, a conservative Republican, is perhaps best known for shouting "You lie!" at President Barack Obama as the latter addressed a joint session of Congress in 2009. Wilson later apologized and was formally admonished by the House of Representatives.
W. Eric Dell, Wilson's chief of staff and counsel, said the congresman was released from the hospital in the early afternoon Saturday and is feeling better.
Wilson said on the radio show he anticipates a speedy recovery and is looking forward to his annual district bus tour rescheduled for September 26-30th. "I truly enjoy fulfilling the pledge I made to be accountable and accessible," he said.
