I have been having fever since last friday night and it has been 7 days from now. Initially started with shiver and fever and vomiting. Now there is no much shivering and just have fever and nausea. All my tests like dengue, malaria,typhoid & jaundice for 3 times and all came up negative and still having fever which goes up to 103-104 and after taking tablets and iv injections it gets reduced. Again after the medicines wear off then it starts again. I am currently taking dolo650, pan40, cough syrup & cefakind 500 antibiotic.
