i had mild fever a few weeks back.  i consulted a doctor and took antibiotic which i presume not enough to my age.  once i completed the antibiotic, i started to have fever a week after the course.  Then I went to the doctor again to have a stronger dose of antibiotic.  After seven days of completing the course, I again had mild fever. What do yo9u diagnose of this condition.  I am 59 yrs with an active life.
Helots is case of fever of long duration (because you took two courses of antibiotics) fever , so the cause of this prolonged fever may be, This includes.1 Typhoid fever, diagnosis can be confirmed by Tidal 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 HBase 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.
