question: Hi doctor, On 16th evening, I suddenly fell sick with symptoms like fever, sudden fatigue, chills, body aches (chest, legs, shoulders, head, eyes, almost all body). I was good during the day except for an itching in the throat. The weakness was so severe that I could not even walk a few steps. I felt like I was going to collapse. Yesterday, I visited a physician who advised me to undergo few blood tests. He thought I am having dengue. Today, I received my blood reports. The dengue tests were negative. But the CBC reports suggest an infection. I still have a similar weakness that I had during the onset of fever. When I walk, I feel like my head is throbbing and it would burst. I almost hold it by my hand to suppress the pain. The body ache seems to be reduced as I am taking Calpol twice a day. Do I really have dengue? Did the test turn negative as I did it before 24 hours of onset of fever? Do you suggest to undergo any other test like chikungunya and yellow fever? Or is it just 'atypical' viral fever? I am currently on Azithromycin once a day, Paracetamol twice a day, and Allegra twice a day.
