answer:

the questionnaire that you filled with all the “yes” responses will be asked by the doctor in order to determine the kind of problems and issues that you are currently facing. the doctor will also ask if there are any other concerns that you want to share that have not been mentioned in the questionnaire  

your doctor would also make sure that frequent appointments are scheduled for regular check ups.
