Yesterday an onset of coughing started, followed by headache and vomiting, I have COPD, but it has never been like this, it reminds me when I had the flu but I have had the flu vaccine this year. I am male 59 yrs old 230#. I have begun blowing my nose and coughing even more, not a little but violently and is followed by me vomiting after the coughing spell.
