My mother has a cough, which keeps her up night and day. She has had this cough for nearly a year. It is getting worse. They have done all kinds of test and can not find anything that helps. About the only thing that has helped as far as getting her relief is hydrocodone, acetaminophen 5-325. I know she can not take this all the time but it does help. Do you know anyone else who might have these symptoms? She is 80 now. But has been a very healthy person. Thank You for your help.
