In early feb I went to the dr for a constant cough and congestion. They put me on a z back. But I never fully got better. Now my cough is worse with sneezing , an itchy throat , body pain, bloody congestion, and headaches . All they tell me is that it ll go away an give me the same meds. But I m by myself with my 9month old son, so I can t afford to be sick. What should I do?
