Viral Myocarditis recovery

I am a 48 yr old male, who was diagnoised with viral myocarditis 4 months ago.  I was admitted to the ER after having flu-like symptoms, difficulty in breathing, and at one point my EF was 12-15%.  I am very active, non-smoker, non-drinker, not overweight, no history of heart/blood pressure problems,  with that being said, Dr. said this has helped in my recovery.  My EF was up to 60-65% on follow-up visit to Cardiologist in Dec.  Was on several med at one point but now am taking Coreg CR, Simvastatin, aspirin, fish oil.  Have been following a low-salt diet as well.  My last EF test revealed it was 49% so Dr suggested I start taking enalapril again as a precaution. Recently I became ill with similiar symptoms but no difficulty in breathing.  Suffering from weakness, jittery, queasiness.  Went back to Cardiologists and had EKG which was normal.  At present, am wearing a 48 hr heart monitor.  I have 3 questions:  Should there be any skin sensitivity/numbness around the heart area?  I've described this to my general dr as well as my Cardio. Both suggests a pulled muscle/inflammation. 2. What about joint/muscle aches/pain? 3. Recovery time/prognosis?
Any response will be appreciated
