4. Chest Pain
Chest pain is something that you should never ignore. It can be very scary to have pain in your chest. If you are experiencing chest pain when you move around and when you breathe more heavily, it could be a sign that you have developed walking pneumonia.
Chest pain can also indicate many other types of health issues including a heart attack. If you are experiencing any type of chest pain when breathing, it is important to go to the doctor right away to rule out heart issues and other more serious conditions.
