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 ?
Unfortunately, there is no way to know for sure if it's a minor viral infection or a more significant bacterial infection (or something else) without getting seen. Since its already been 4 days, I wouldn't wait too much longer to get checked by a doctor. Especially if you are having specific symptoms such as a productive cough, burning when you urinate, chest pain, abdominal pain, or feeling really sick (e.g. severe body aches). If you are not having other symptoms, you could probably wait another day or 2, but certainly no longer than that. Hope this helps.
