Have rheumaticfever in heart since last year.i always get tired easily,sensitive in crowded places&heat.is it normal to those who have this?

Valve problem: Rheumatic heart disease typically manifests as a problem due to deformed valves. It's difficult to determine whether you are saying you have active rheumatic fever or the resultant damaged valves. Blood tests, a careful history and physical exam, chest X-rays and an echocardiogram can answer the question. A cardiologist could help clarify this.

Rheumatic fever: your complaints are not normal. See your cardiologist for a reevaluation of your symptoms
