Is It Normal To Feel Achy From The Flu?

October 31, 2023

Alongside flu’s well-known symptoms of fever, cough, and congestion, many individuals who have experienced the flu have also complained of body aches and pains. This article will explore the connection between the flu, body aches, and the causes. For same-day flu shots and flu treatment, visit the walk-in clinic at AFC Urgent Care Thornton. You can simply walk-in any day of the week, or plan your visit in advance by reserving your spot online.

Causes and Symptoms of the Flu        

The flu, or influenza, can lead to various symptoms and complications. The flu is caused by influenza viruses, primarily influenza A and B. These viruses can mutate over time, leading to seasonal flu outbreaks. That’s why it’s crucial to receive a flu shot each year.

Here are some common symptoms associated with the flu:

  • Fever
  • Cough
  • Sore throat
  • Runny or stuffy nose
  • Body aches
  • Fatigue
  • Headache
  • Chills and sweats
  • Gastrointestinal symptoms

It's essential to note that flu symptoms can vary in severity from mild to severe, and complications, such as pneumonia and bronchitis,. The flu is highly contagious and spreads through respiratory droplets when an infected person coughs, sneezes, or talks.

Why the Flu Can Cause Body Aches

The flu can cause body aches primarily due to the body's immune response to the viral infection. When the influenza virus enters the body, the immune system recognizes it as foreign and mounts an immune response. Part of this response involves the release of inflammatory substances called cytokines. These cytokines play a crucial role in fighting the virus but can also cause inflammation in the body's tissues, including the muscles.

The immune system's response to the flu can lead to inflammation in various parts of the body, including the muscles. This inflammation can cause pain and discomfort, leading to body aches and muscle soreness associated with the flu.

Influenza Prevention and Treatment

Influenza prevention and treatment strategies are essential to reduce the risk of contracting the flu and manage its symptoms effectively. 


  • Flu vaccination
  • Good hygiene practices
  • Respiratory hygiene
  • Avoid close contact
  • Face masks
  • Keep surfaces clean


  • Antiviral medications: A healthcare provider can prescribe antiviral drugs like oseltamivir (Tamiflu) and zanamivir (Relenza) to treat the flu.
  • Rest: Avoid strenuous activities, get plenty of sleep, and allow your immune system to fight the virus.
  • Stay hydrated: Drink plenty of fluids like water, herbal teas, and clear broths. 
  • Over-the-counter medications
  • Humidifier: Using a humidifier in your room can ease congestion and soothe a sore throat.
  • Isolation: If you have the flu, stay home to prevent spreading it to others. Isolate yourself from family members and avoid close contact until you are fever-free for at least 24 hours without using fever-reducing medications.
