Coughing since 1year
My mom is suffering from cough. Whenever she eats something the cough starts. This has been happening since one year. She has consulted doctors and undergone the prescribed tests, by God's grace no problem has been detected. Doctors have prescribed her with cough syrups and as soon the intake. of syrups stops the problem reoccurs. Please suggest what to do, as she is old and this coughing is causing alot of problem to her.
