I have had a persistent cough on and off for several years! I ve had chest x-rays, sinus CT scans, and recently had a large benign tumor removed from my thyroid along with the right side of the thyroid. I was hoping the removal would take care of the cough, but a week after surgery I got the flu and now I m still coughing. I ve been doing an Albuterol inhaler religiously along with taking Benzonatate three times a day and Delsum cough medicine every 12 hours - nothing seems to help. I m at my wit s end and ready to find an accupuncturist or hypnotist because I m wondering if my throat muscles are just so used to coughing that they just can t stop! Any suggestions?
