Cough and drip for the 2 years she has lived with us. What kind of specialist should we take her to? Family doc is only giving her OTC meds that is not helping. Her cough is getting worse and she can use a box of kleenex in one day. I hear her coughing off and on all night. Primary care doctors has her on muscinex and nose spray and meds for acid reflux which I am not sure she needs. Also takes aricept and Vitiamn D.
