Absence of fever, although a low grade fever may occasionally be present
Tenderness or soreness in the chest with coughing
If a fever is present (temperature above 100.4 degrees Fahrenheit), and there are signs that your general well being is affected, such as loss of appetite and generalized achiness, then pneumonia may be the cause of your symptoms. Pneumonia usually requires the use of antibiotics.
