Regarding Hantavirus - What Is The Length Of Time From

Regarding hantavirus - What is the length of time from the onset of symptoms to the onset of pulmonary symptoms? Also, do people with hantavirus always have a fever? For the past five days or so I've had a headache, neck pain, joint and muscle pain and am a bit concerned as last month I did some cleaning out of out buildings where could see evidence of mice infestation. I have had no intestinal problems or nausea. Do I need to see a doctor?
