Hai,
If the total duration of your symptoms is of more than 3 days and still high feverish, then it's better to investigate.
Please do basic blood , urine tests and then review. Meanwhile you can take paracetamol tablets for fever (provided no known drug allergy). Based on the investigation reports it's better to decide the treatment after getting a diagnosis.
May I suggest,
1. Tab. Paracetamol 650mg 1--1--1 × 2 days
2. Plenty of oral fluids (minimum of 3 liters per day)
Next Steps
please do,
1. CBC
2. Urine R/E
3. SGOT, SGPT
Health Tips
if symptoms worsening immediately consult with your nearest hospital. its always better to consult to the doctor in direct and to get diagnosed and to start treatment.
