Thank you for your question! First of all I would like to assure you that pericarditis is mostly not a dramatic illness, except for its acute pains; and except when there is evidence of the involvement of an important mass of the adjacent myocardium; if no myocarditis is present; no clinically important fluid has remained in the pericardial space if not ever at all; and no primary pericardial disease is suspected; then your daily physical activity could be restored depending only on the clinical presence of pain; I recommend you not to hurry up, but to listen to your doctor because he knows all these dilemmas I explained to you; If the chest pain with disappear I believe there will be no more limitation. Hope to have been helpful to you, Best regard, Dr. Iliri
