Key Symptoms: Difficulty breathing or shortness of breath Cough, often productive with sputum that may be blood-tinged Chest pain or tightness Fever or chills if secondary infection develops Rapid breathing and increased heart rate Feeling of suffocation or tightness in the chest General malaise or fatigue Potential signs of hypoxia, such as bluish lips or face
