I am a 42 year old female. About 6 years ago I started to cough (with nasal drip) after every meal and drink. I had different tests done, but the doctors don't know what is going on. They thought that it was Acid Reflux, or that it had something to do with my hiatal hernia, but all of the tests that they have done came back fine. Now it is so bad that I cough even when I don't eat or drink. I am starting to get on everybody's nerves, including my own. All I want is to be able to go through the day and the night without coughing. Any help would be greatly appreciated.
