My husband has symptoms of excess mucus, cough, wheezing, and stuffy nose but no fever or chills. Not a cold.? He does not seem to have a cold as these symptoms have been going on for 4 months now.  He has everyday clearing of his throat and unproductive cough, he seems to have postnasal drip.  We have been to the doctor twice, the symptoms continue.  We have tried over-the-counter medications as well as prescriptions.  What could this be?  We think it is reflux but all the measures have not helped.  I'm afraid he's going to injure his throat because of the hard coughing with trying to bring up mucus.  His respiratory function tests were normal.

Summarized question: What are the symptoms of and treatments for acid reflux?
