Thanks for posting your query.
With the available described symptoms, there appears to be possibility of Acute upper respiratory tract
infection with superimposed secondary bacterial infection.
There also appears to be possibility of infection foci in tonsils also causing persistent halitosis
You should consult with internal medicine specialist/ ENT surgeon and should go for thorough check up.
You should also go for complete blood count
. erythrocyte sedimentation rate
, chest x ray
, throat swab culture & sensitivity.
You should take complete antibiotic therapy, decongestants, mucolytics.
Avoid sour, oily foods and cold drinks.
Perform gargles three times in a day; a glass of lukewarm water with a pinch of salt.
