Can a Sinus Infection Cause Body Aches?

March 2, 2025

A sinus infection, or sinusitis, is known for causing congestion, facial pressure, and headaches, but can it also lead to body aches? The answer is yes– especially if the infection is severe or prolonged. Body aches during a sinus infection are often a sign that your immune system is working hard to fight off the infection. In this blog, we’ll explore the connection between sinusitis and body aches, as well as when it might be necessary to seek medical attention.

How a Sinus Infection Can Cause Body Aches

Sinus infections occur when the sinuses become inflamed due to a viral, bacterial, or fungal infection. While congestion and sinus pressure are the most common symptoms, sinusitis can also cause body aches for several reasons, including:

  • Immune System Response: When your body fights an infection, it releases inflammatory chemicals that can cause muscle aches and joint pain.
  • Fever and Inflammation: A bacterial sinus infection can lead to fever, which often brings chills, fatigue, and body aches.
  • Dehydration: Sinus infections can lead to dehydration, which may contribute to muscle cramps and body discomfort.
  • Poor Sleep Quality: Congestion and sinus pressure can make it difficult to sleep, leading to fatigue and sore muscles.

Common Symptoms of a Sinus Infection

In addition to body aches, a sinus infection may cause:

  • Nasal congestion and pressure
  • Runny or stuffy nose
  • Headache or facial pain
  • Postnasal drip
  • Fatigue
  • Fever (bacterial infections)
  • Cough

When Are Body Aches a Concern?

Mild body aches are common with sinus infections, especially if the infection is caused by a virus. However, if you experience severe body aches, a high fever, or persistent fatigue, it may indicate a more serious infection, such as the flu or another viral illness. You should consult a healthcare provider if your symptoms persist or worsen. If body aches are making your sinus infection feel worse, try these remedies:

1. Stay hydrated by drinking plenty of fluids to thin mucus and prevent dehydration

2. Use a humidifier as moist air can help ease congestion and soothe sore muscles

3. Allow your body time to heal by getting enough rest

4. Take over-the-counter pain relievers to reduce inflammation and body aches

5. Apply a warm compress to your sinuses or sore muscles to help ease pain
