I think I caught it at an auction, with in 48 Hr of getting home it had me. My chest feel hot and dry like I jut ran a mile on a 90 degree day. Cough, fever, headache, dizziness, lethargy, tiredness, muscle stiffness and soreness. I if you have or have had it you know what it is like if not then the fun awaits you. I am on day 4 and am only back to full strength by 50 percent I should have this beat by now so what ever this flu is it is tuff.
