What Could Cause Sudden Chills Without Any Fever Despite Keeping Warm With Blankets?
Viral infection, malaria, UTI should be ruled out.
Detailed Answer:
Hi,
It is possible to have chills without hyperthermia (fever).
And common causes for this are
1. Viral infection
2. Malaria
3. UTI (urinary tract infection).
So you should definitely undergo complete blood count (CBC).
This will give some idea about the etiology.
