If you do not have a fever
you do not have that. So do not worry about that and do not try to convince the doctor for what you do not obviously have. Try and tell him all the problems you have and get your self treated for that. If for example you have some body aches, cold
etc tell him that you have all those and get treatment for that rather than trying to convince him about the fever.
Continue to ask further queries as required.
Hope this helps.
