question: I am a 70 years old male. I have fever of about 100 F for last 4 days along with mild shivering and general weakness, I have been taking rest and paracetamol 250 mg every 6 to 8 hours. Fever comes down within 2 to 3 hours of medication and goes up again within 6 to 8 hours of taking medicine. Is it viral fever and will be okay in 5 to 7 days without any other intervention ?
