Early Warning Signs
Initial symptoms of myocarditis can be vague, such as fatigue, body aches, or mild chest discomfort. These may appear alongside symptoms of a recent viral infection like fever or sore throat. Because these signs are common in many illnesses, myocarditis can often be overlooked in its early stages.
Progressive Symptoms
As myocarditis progresses, more noticeable symptoms can develop, including shortness of breath, heart palpitations, or swelling in the legs and feet. These symptoms indicate that the heart is struggling to pump effectively, which could lead to heart failure if left untreated.

Severe Manifestations
In severe cases, myocarditis can lead to life-threatening complications such as cardiogenic shock or sudden cardiac arrest. These situations require immediate medical attention. Recognizing these severe symptoms early can be critical for survival and recovery.
