[62F] Experiencing sudden onset of fatigue and headache

What might be happening

Based on the information you've provided, possible explanations for your symptoms include:

• Common Cold: This is a viral infection of your nose and throat. It's usually harmless, although it might not feel that way. Many types of viruses can cause a common cold. Symptoms can include runny or stuffy nose, fatigue, and headaches.

  • Treatment for a common cold is usually supportive, including rest, hydration, and over-the-counter medications for symptom relief.

• Influenza (Flu): This is a viral infection that attacks your respiratory system — your nose, throat and lungs. Influenza is commonly called the flu, but it's not the same as stomach "flu" viruses that cause diarrhea and vomiting. Symptoms can include fatigue, headaches, and a runny or stuffy nose.

  • Treatment for the flu can include antiviral medications if started early, rest, hydration, and over-the-counter medications for symptom relief.

• Sinusitis: This is inflammation or swelling of the tissue lining the sinuses. This can cause headaches and a runny or stuffy nose.

  • Treatment for sinusitis can include nasal decongestants, antibiotics if a bacterial infection is suspected, and pain relievers for symptom relief.

Please note that these are possible explanations and not a definitive diagnosis. It's important to consult with a healthcare provider for an accurate diagnosis.

What you can do

1. Rest and hydrate: Make sure you're getting plenty of sleep and drinking lots of fluids. This can help your body recover from any potential infections.

2. Over-the-counter medication: Over-the-counter cold, flu, or sinus medications may help alleviate some of your symptoms.

3. Monitor your symptoms: If your symptoms worsen or persist for more than a week, it's important to seek medical attention.

What you should look out for

Reasons to seek urgent medical attention:

• If you develop a high fever (temperature over 100.4°F)
• If you have difficulty breathing
• If you experience severe or worsening headache
• If you have persistent vomiting or cannot keep fluids down
• If you experience confusion or changes in mental function
