Why The Flu Can Cause Lower Back Pain
The flu is a viral infection that triggers an intense immune response. As your body fights off the virus, it releases inflammatory chemicals that can lead to widespread muscle aches and joint pain. For many people, this inflammation is especially noticeable in the lower back, where muscles are already prone to strain and stiffness.
Other contributing factors also include:
- Fever and dehydration, which can increase muscle soreness
- Prolonged bed rest, leading to stiffness in the back muscles
- Coughing, which can strain the lower back over time
How Long Does The Pain Typically Last?
For most people, lower back pain related to the flu improves as the infection runs its course. The discomfort usually:
- Begins within the first couple days of flu symptoms
- Peaks during the height of the illness when fever and body aches are strongest
- Subsides within 5 to 7 days, though lingering soreness can last up to 2 weeks in some cases
If lower back pain persists longer than 2 weeks or becomes severe, it may not be caused solely by the flu and should be evaluated by a healthcare provider.
Tips For Relieving Lower Back Pain During The Flu
Managing back pain while you’re sick can make recovery more comfortable. Try these tips:
- Stay hydrated: Fluids help reduce muscle soreness and prevent dehydration
- Use heat therapy: A heating pad or warm bath can relax tense muscles
- Gentle movement: Light stretching or short walks can reduce stiffness if you’re able
- OTC pain relievers: Medications like acetaminophen or ibuprofen may ease both flu symptoms and muscle pain
- Supportive rest: Use pillows to maintain proper spinal alignment when lying down
While some back pain is normal with the flu, certain signs may indicate a more serious issue. Contact a healthcare provider if you experience severe or worsening pain, difficulty urinating, shortness or breath or chest pain, as well as back pain lasting longer than 2 weeks after other flu symptoms resolve.
