Hello
This is case of fever of long duration ( because you took two courses of antibiotics ) fever , so the cause of this
prolonged fever may be, these includes.
1
Typhoid fever , diagnosis can be confirmed by
Widal test and serology test. This is a case of fever of long duration and may have not responded to antibiotics prescribed by your doctor.
2
Tuberculosis is another reason of such fever . Diagnosis can be confirmed by X RAY chest with blood for C B C & E S R ( if very high e.g. > 90 mm suggestive of tuberculosis or any other chronic illness).Tuberculin test is also suggestive.
3 Jaundice is another cause of such fever . Get in blood for HBASG A B C E , (
hepatitis most common cause).
There are so many other causes of such fever as carcinoma , anemia ( general weakness ) , malaria , dengue.
In my opinion consult another physician and get his opinion as mentioned above.
Hope this will be helpful for you.
Don't take further any other antibiotics without proper diagnosis .
