What causes persisting fever?
Patient: I am suffering from fever since last whole month.Its between 99 and 100.I dont have any other problem like flu,cough etc but just have headache and weakness now.I had series of tests like typhoid,LFT,UDR etc but they all are normal. Whenever i took panadol,fever goes down but after sometime it reaches between 99 & 100 again. At night it becomes normal but with the rising day it rises. I got married 4 months back but i am not expecting at the moment. Doctor: HIGreetings from Dr.Divakara.PThanks for posting your query.     Well if fever is persisting then it means that there is still persisting infection. You have not been completely evaluated with tests. You need to be done certain more test which shall detect the cause of fever.    In that regard I would like to advise certain more tests , kindly get these tests done and revert back to me . ( You can skip the tests if these were done prior ).   Monteux test, Blood culture sensitivity , Urine Culture sensitivity , IgM Leptospira Abs, Brucella Antigen test, Chest X ray, X ray PNS. Hope this information was useful to you. Any clarification feel free to ask.
