My mother from past 20 days is suffering from chills sometimes with or without fever,her cbc report show elevated esr 60, and she also has dry cough from 10 days. but her chest xray was done 2 days before & is normal?

Beats 20 Days InJail: Just like anywhere else in life, a person can look good on paper and turn-out to be the opposite. You can have a miserable cold or flu and nothing too alarming shows-up on any tests, in this case the x-ray.
