Walking pneumonia is a mild form of pneumonia that rarely requires hospitalization and is unlikely to be life-threatening, according to FamilyDoctor.org. As with any case of pneumonia, however, walking pneumonia can worsen without treatment, especially in people who are 65 or older and have cardiopulmonary problems.
Emergency services are necessary if the individual experiences crushing chest pain, profound difficulty breathing, and faintness in addition to coughing up significant amounts of blood, reports WebMD. Less extreme symptoms such as coughing up blood-tinged mucus, a fever with chills and shortness of breath still require immediate medical attention. A wait-and-see approach can work with pneumonia in mild cases, but it is important to be vigilant and seek medical care if symptoms worsen.
