I went to the dr 4 days ago, thought and felt like I had the flu. Chest tightness, cough, chills, fever, eyes watery, so miserable. Nose test came back negative and the dr said I had bronchitis. Gave me a steroid shot, z pack, steroid pack, and benzonatate 100mlg 3x daily. My cough is so bad, throat feels like its been thru a meat grinder RAW, chest hurts from coughing so much. I'm so miserable. Need advice please
