This is the second year that I get a cough a week or two after i get a flu shot. I cough so hard I almost pass out. I ve seen Drs., endlnostopy, a swallow test, an ENT, a heart Dr., an Allergist. No one has the answer. I run no fever , I feel fine, but I cough. It is not contagious, my wife or grandkids do not get it. They changed my blood pressure medicine, that wasn t the answer. I ve been on different inhalers. I ve been on steroids and antibiotics. They have tried different cough syrups. No One seems to know what it is. My wife works at a store here in town that has run into 2 or 3 people that have had the same thing as myself and they can t find out what it is either. I am 63 years old , never smoked, I m probably 50 lbs. over weight. If you an answer for me I would appreciate it. Thank you, Ron Miller.
