Okay since the end of June 2017 I have had chest congestion, runny nose, spitting up, coughing up brownish to greenish thick phlegm. My chest has a rattle to it. I don t have asthma, at first they treated it as an upper chest infection, put me on two rounds of ABT but it still continues. I ve never had this before. I went back to the ER and this Dr. said it was allergies put me on mucinex, Albuterol inhaler, nasal spray, and it s still not better.
