I have been sick for about 3 weeks now. I went to the dr and was told I had chest congestion and a sinus infection. I was giving coughing meds, inhaler, and antibiotics. That was 2 1/2 weeks ago and now for the last 3 days I have horrible pain in my rib cage and back areas. I still have coughing fits with wheezing, itchy throat, and a metallic taste in my mouth. Plus still coughing up yellow mucus???
