I started wheezing, coughing, and spitting up phlegm (yellowish
in color) about 8 months ago. Since then I have been on various rounds of antibiotics, prednisone, cough syrups, singular, symbicort, albuterol etc. I had been treated at the allergy clinic years before for allergies and asthma. I have had to take about 8 days of 10mg prednisone about 4 -5 times in the last 8 months. It is about the only thing that helps my coughing and spitting up of phlegm.
