To find the cause of your cough will require medical consultation, as there are many potential causes. That you “bring up my food and other fluid also” could be the result of harsh coughing but, on the other hand, bringing up the food could be a sign of a swallowing problem that is actually causing the cough.
Diagnosis of the cause of chronic cough requires careful attention to detail by the examining doctor. You might begin with your primary care physician but, if no specific cause of cough is evident to him/her the two of you would be wise to consider seeking a second opinion from a lung specialist with a special interest in chronic cough or from a physician at a Cough Clinic, such clinics usually to be found at University Medical Centers.
