Thanks for using Healthcaremagic,
You should understand that fever with chills indicate some disease in body usually infection which could be Urinary tract infection
, Pneumonia, Malaria, or even viral infection.
If you do not have any specific issue and fever is better with paracetamol
you can wait a day or two till your appointment is there and in the mean time you may take Tylenol to make you comfortable.
If there is something alarming like breathing difficulty, altered sensorium, severe pain
it is better to seek medical help
Hope information helps you.
Wish you good Health.
