I have had a chronic cough for more than 6 months and so far, my doctor has not been able to diagnose my problem. I just had a series of tests that confirmed I had some signs of acid reflux and prilosec was prescribed. I have been on the medicine for several weeks but have not found any relief. I do not believe acid reflux is the cause. I would love to hear from others that have had such symptoms and suggestions of potential causes.
