So I've been feeling fever since yesterday night. And today, like, now it is 100 degree Fahrenheit. And I am having very runny nose and sore throat as well. Also... I'm having a severe back pain. And you know my body is aching. So... What could it be? Well, then how do I go about it?

I now have thorough information from authoritative medical sources. Here is a full, clear answer:
What's Likely Going On
Your symptom profile - fever (100°F/37.8°C), runny nose, sore throat, body aches, and back pain - fits influenza (the flu) very well. The key distinguishing feature of flu vs. a common cold is the systemic involvement: body aches, back pain, and fever hit hard and fast with flu, while a cold stays mostly nasal/throat with milder or no systemic symptoms.
Here's how the two compare (from Park's Textbook of Preventive and Social Medicine):
| Feature | Influenza | Common Cold |
|---|---|---|
| Fever | Yes, typically 100-102°F+ | Mild or absent |
| Body aches | Moderate to severe | Mild |
| Sore throat | Yes | Yes |
| Runny/stuffy nose | Yes | Yes (often more prominent) |
| Onset | Rapid (hours) | Gradual |
| Fatigue | Marked | Mild |
Other possibilities to keep in mind:
- COVID-19 - shares most of the same symptoms. Loss of smell/taste is more characteristic of COVID but not always present. A home antigen test can quickly rule this in or out.
- Strep throat - causes fever and severe sore throat but usually WITHOUT runny nose; body aches are less prominent.
- Common cold - possible but your degree of body aches and back pain leans more toward flu.
What You Should Do
Right now (home care):
- Rest - Your body needs it. Stay home, don't push through.
- Hydrate aggressively - Fever and sweating cause fluid loss. Water, oral rehydration drinks, warm broths, herbal teas. Aim for more than usual.
- Fever and pain relief - Take paracetamol (acetaminophen) or ibuprofen for your fever, sore throat pain, and body aches. Follow label dosing. Do NOT take aspirin (risk of Reye's syndrome if viral illness).
- Sore throat - Gargle with warm salt water. Throat lozenges also help.
- Runny nose - Saline nasal drops can relieve congestion. OTC decongestants (pseudoephedrine, oxymetazoline nasal spray) can help but use sparingly.
- Warm compress or heating pad for back/muscle pain gives good local relief.
Should you get an antiviral (Tamiflu/oseltamivir)?
According to Harrison's Principles of Internal Medicine (22nd Ed.) and Tintinalli's Emergency Medicine, antiviral drugs like oseltamivir (Tamiflu) are most effective when started within 48 hours of symptom onset - they shorten illness by about 1-2 days and reduce complication risk. Since your symptoms started last night, you are still within that 48-hour window - this is the time to act if you want antivirals.
Antivirals are strongly recommended if you fall into a high-risk group:
- Age 65+
- Pregnant
- Asthma, COPD, diabetes, heart/kidney/liver disease
- Immunocompromised
- BMI ≥40
If you're a healthy adult with no risk factors, antivirals are optional (they reduce duration by ~1 day) but still worth considering since you're in the window.
To get antivirals, you'll need a prescription - call your doctor or visit an urgent care clinic today.
Warning Signs - Go to ER Immediately If:
These signs suggest serious progression and need urgent medical attention (per Park's Textbook and Rosen's Emergency Medicine):
- Difficulty breathing or shortness of breath at rest
- Chest pain
- Confusion, altered mental status, hard to wake up
- Lips or fingernails turning blue
- Fever not going down despite paracetamol/ibuprofen or fever rising above 103°F (39.4°C)
- No improvement after 72 hours or getting worse after initial improvement
- Severe vomiting / not keeping fluids down
- Decreased urination (sign of dehydration)
Quick Summary Plan
| Step | Action |
|---|---|
| Today | Rest, fluids, paracetamol/ibuprofen for fever+pain |
| Today | Do a COVID home test if you have one |
| Today (urgent if in window) | Call doctor/urgent care about oseltamivir |
| Throat | Warm salt water gargle, lozenges |
| Back/body pain | Warm compress, ibuprofen |
| Monitor | Watch for the red-flag warning signs above |
Most flu cases in otherwise healthy adults resolve in 5-7 days, though fatigue can linger 1-2 weeks. Feel better soon! If symptoms worsen or don't improve in 2-3 days, see a doctor in person.

I had taken Dolo 650. Uh, in the morning, like around at 10:30 AM, and right now it's around 3:30. Should I take another one because I'm already at 100 degree Fahrenheit?

Yes, go ahead and take another Dolo 650 now. Here's the clear breakdown:
Dolo 650 (Paracetamol/Acetaminophen 650 mg) - Dosing
| Details | |
|---|---|
| Standard adult dose | 325-1000 mg every 4-6 hours |
| Your last dose | 10:30 AM |
| Time now | 3:30 PM = 5 hours later |
| Safe to take? | ✅ Yes - well past the 4-6 hour interval |
| Max dose per day | 4 g (4000 mg) under doctor guidance; 3 g (3000 mg) for self-medication |
(Source: Tintinalli's Emergency Medicine)
Your Running Dose Count (to stay safe today)
If you're tracking your doses today:
- Dose 1: 10:30 AM - 650 mg
- Dose 2: 3:30 PM - 650 mg ← take this now
- Dose 3: Can take at ~8:30-9:30 PM if still needed
- Dose 4: Can take before bed if needed
Total today so far = 1300 mg - well under the 3000 mg self-medication limit.
One thing to note about 100°F (37.8°C)
A temperature of 100°F is a low-grade fever. Paracetamol will bring it down, but don't be alarmed if it stays slightly elevated - that's your immune system working. Take the tablet now, drink a large glass of water with it, and rest.
If fever climbs above 103°F (39.4°C) or doesn't respond to Dolo at all, that's when you'd want to see a doctor.
