Could You Have Walking Pneumonia? 10 Signs to Look For

7. Flu-Like Symptoms

It can be difficult to distinguish between the common flu and walking pneumonia due to the similarity of symptoms. Just like the flu, walking pneumonia can cause chills, muscle pain, coughing, and a sore throat. Some symptoms can help professionals and patients differentiate between the two, however. Walking pneumonia is more likely to cause only a dry cough, while the flu can lead to both a dry cough and phlegmy expectoration. The flu also tends to cause more severe physical aches.
