Answer to Why won't my fever go away even after taking medication from the doctor? by Michael Mangold
The primary answer is that the antibiotic isn't working. It may be due to several reasons including local drug resistance and wrong coverage for that specific bacterium. If the fever hasn't abated after 3–4 days of therapy, go back to your doctor.
Other reasons include that you have a viral infection instead, and lastly that your doc doesn't know what's really going on. I would call that “ignorance” or 'lack of experience” before labeling them a “quack.”
