[29F] Experiencing sudden extreme fatigue and persistent headache

What might be happening

Based on the symptoms you've described, here are a few possibilities:

• Influenza (Flu): The flu is a common viral infection that can be deadly, especially in high-risk groups. Symptoms include fatigue, body aches, headache, fever, and congestion.

  • Treatment usually involves rest, fluids, and over-the-counter medication to manage symptoms. Antiviral drugs may be prescribed in some cases.

• Common Cold: This is a viral infection of your nose and throat. It's usually harmless, although it might not feel that way. Symptoms can be similar to the flu but are generally milder.

  • Treatment involves rest, hydration, and over-the-counter cold remedies.

• COVID-19: This is a viral infection caused by a new coronavirus. Symptoms can range from mild to severe and can include fatigue, body aches, headache, fever, and congestion.

  • Treatment depends on the severity of the symptoms. Mild cases usually recover with supportive care (rest, hydration, over-the-counter medication). Severe cases may require hospitalization.

• Sinusitis: This is an inflammation or swelling of the tissue lining the sinuses. Symptoms can include headache, facial pressure, and congestion.

  • Treatment usually involves managing symptoms with over-the-counter medication, nasal sprays, and sometimes antibiotics if it's a bacterial infection.

What you can do

You should seek care from a healthcare professional for a formal diagnosis and treatment. In the meantime, here are some things you can do:

1. Rest and hydrate: These are important for recovery from most illnesses.
