“Can you fully recover from myocarditis?”

Yes, but you need to see your PCP or cardiologist for treatment and follow up.

Full recovery from myocarditis is expected in the majority of cases.

Yes, you can but it depends on the presentation and cause. Myocarditis is commonly caused by viral infections but sometimes bacterial, fungal, parasitic infections, cardiotoxins (including alcohol), hypersensitivity reactions to medications, autoimmune diseases, and radiation. The presentation varies from no symptoms to fulminant myocarditis. The majority of asymptomatic myocarditis is self-limited without overt sequelae. A minority of patients who were initially asymptomatic may develop heart failure and rhythm disturbances. In symptomatic patients, predictors of poor outcomes include reduced pumping function of the left ventricle, serious arrhythmia, the requirement for mechanical or pharmacologic circulatory support.

Yes you can, some can develop Cardiomyopathy though.
