Hello doctor,

My fever has now lasted six days. I took Paracetamol 500 mg and 650 mg and went to the hospital twice, but my fever did not go away. I am also shivering and coughing.



Welcome to

I read your query and understand your concern.

Please answer the following questions for me to get a clear picture of your concern:

How is your fever? Does it last all day, only in the evening, or only in the morning? Is it a low (38 degree Celsius or 100 degree Fahrenheit), moderate (38 to 39 degree Celsius,100 to 102 Fahrenheit), or high (102 degree Fehrenheit and above) grade? What is its frequency, and how long does it last after being reduced with Paracetamol? What other symptoms are there besides fever? Is there any shivering, coughing, or loose motions associated with urination, or is there anything else? Have you done any laboratory tests? Have you taken any other treatment besides Paracetamol? I suggest you do the following investigation

1. Urine culture test.

2. CBC (complete blood count).

3. PS (peripheral smear) for MP (malarial parasite).

4. NS1 (nonstructural protein) antigen.

5. Widal test.

6. Liver function test.

7. Tuberculin test.

The cause of the fever can be due to the following conditions:

1. Respiratory tract infection.

2. Urinary tract infection.

3. Malaria.

4. Typhoid.

5. Dengue.

Please gather the reports and follow up here for acurate treatment.

Hope this helps.

Thank you.
