My recommendations

Provisional diagnosis

Viral Upper Respiratory Infection (Based on the symptoms of sore throat, low-grade fever, and runny nose without white patches on tonsils, a viral etiology is most likely.)

Differentials

Here are top 6 differentials to consider. Estimated probabilities are mentioned along with. Sum of probabilities can be more than 100, because probabilities are assigned to each differentials individually.

1.Allergic Rhinitis (20%)
2.Bacterial Pharyngitis (10%)
3.Influenza (10%)
4.Acute Sinusitis (5%)
5.Mononucleosis (5%)
6.Non-Allergic Rhinitis (5%)

Suggested medications

Treatment is supportive as symptoms suggest a viral etiology. Antibiotics are not indicated at this time.

Paracetamol:
500 mg orally every 4-6 hours as needed for fever and sore throat

Phenylephrine:
10 mg orally every 4 hours as needed for nasal congestion

Chlorpheniramine:
4 mg orally every 4-6 hours as needed for runny nose

Next line: If symptoms worsen or do not improve in 5-7 days, consider re-evaluation for possible bacterial infection or alternative diagnoses.

Investigations & monitoring

No investigations are indicated at this stage as the clinical presentation is consistent with a viral upper respiratory infection.

Decision tree

Advise

Follow-up if symptoms worsen or do not improve within the expected time frame.

Ensure adequate rest and hydration to support immune function.

Gargle with warm salt water to soothe sore throat.

Use a humidifier in the room to ease nasal congestion.

Avoid exposure to known allergens and irritants that may exacerbate symptoms.

Explanation behind my opinion

The management plan is based on the clinical presentation and the likelihood of a viral etiology for the upper respiratory symptoms.

Empirical antibiotic therapy is not initiated due to the absence of signs suggestive of bacterial infection.

Over-the-counter medications are recommended for symptomatic relief.

Patient education on self-care and monitoring is emphasized to identify any progression that may warrant further medical evaluation.

Please note that Medicine is a complex discipline so Artificial intelligence is equally prone to committing mistakes just like a human physician. However, as a human physician can physically examine you and can get more information as needed, you should trust your doctor's judgement more than this report.
