<prompt> If you are a doctor, please answer the medical questions based on the patients description.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.  <response>: 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.Dont take further any other antibiotics without proper diagnosis.
