I had a high fever, and muscle soreness. Then I started getting congested, so I went to the doctor. They checked for the flu, and took a chest x-ray. They said both looked fine. They put me on antibiotics because my phlegm was discolored. My fever left, and muscle ache's. Now I've been coughing up phlegm. Its been a week since I've been on antibiotics, and a week and a half I've been sick. My congestion is not getting better.
