[20M] Experiencing fatigue, body aches, and upper respiratory symptoms

What might be happening

Based on the symptoms you've provided, the most likely diagnoses include:

• Common Cold: This is a viral infection of your nose and throat (upper respiratory tract). It's usually harmless, although it might not feel that way. Symptoms might include a runny or stuffy nose, sore throat, cough, congestion, slight body aches or a mild headache, sneezing, low-grade fever, and generally feeling unwell (malaise).

  • Treatment for the common cold is typically supportive, including rest, hydration, and over-the-counter cold remedies to manage symptoms.

• Influenza (Flu): This is a common viral infection that can be deadly, especially in high-risk groups. The flu attacks the lungs, nose, and throat. Symptoms are similar to the common cold but are usually more severe and come on suddenly. Fatigue can be particularly pronounced.

  • Treatment may include antiviral medication if started early in the disease course, as well as supportive care.

• Mononucleosis: Often called "mono," this is an infection usually caused by the Epstein-Barr virus. Symptoms can include fatigue, sore throat, fever, inflamed lymph nodes, and headaches.

  • Treatment is supportive, as the disease is viral and typically self-limited.

What you can do

1. Rest and hydrate: Regardless of the cause, getting plenty of sleep and staying well-hydrated are key to recovery.
2. Over-the-counter remedies: Over-the-counter cold remedies can help with symptoms of both the common cold and the flu.
3. Seek medical attention: If your symptoms persist for more than a week, worsen, or you become short of breath, seek medical attention.

What you should look out for

• Difficulty breathing or shortness of breath
• High fever (>101.3°F)
• Severe headache or neck stiffness
• Symptoms that persist for more than a week or worsen
