Really bad chills. Sore throat body and muscle weakness been about 40 hours. No fever?

Doctor can evaluate. New throat pain can be from a strep throat infection (antibiotics are needed), a cold or influenza (antibiotics usually not used), or from some other cause such as allergies or irritants (but they wouldn't cause chills). A person sees the doctor if the sore throat is bothersome, recurrent, or doesn't go away quickly (mainly to check for strep throat).
