I've been tested for influenza A and B, swine flu, mono, strep-all of them came back negative. I also don't have pneumonia or bronchitis. For the past 2 weeks, I've had a sore throat, fever, chills, migraines, cough, congestion, and am exhausted. I've been drinking plenty of fluids, trying to get a lot of rest, and am taking Advil and Tylenol. I have not been feeling any better. Any ideas/suggestions??
