My mother has had a terrible cough for over 8 weeks, She is 91 and in a rehab facility after a heart attack in November. She has been on prilosec for years for her acid reflux,Now she is unable to even talk without coughing . Nothing seems to heal the cough, including breathing treatments, cough medicine etc. I believe she may have a cough response to her GERD and no one there thinks it is true since she is on prilosec. I was wondering how to start the conversation with her physician. She is giving up hope to get better, has lost her appetite because of this constant coughing. What kind of doctor should we take her to? By the way her lungs are perfectly clear.
