question: For the past 2 months I have had a severe cough. I cough up a lot of mucus and sometimes I cough so hard I have vomited. This is accompanied by pressure and pain in my chest and recently pain in my upper back and shoulder blades as well. I also have had reoccurring flu and cold like symptoms, and I am drained of energy. I went to the doctor who said it was allergies and gave me sinus medication and mucinex. The only thing that seemed to help a little was the mucinex the sinus medication made me feel worse. I am certain this is not allergy related since the medication did not work and I have never had allergies before. I am starting to become very concerned what could this be?
