I Had A Flu And Two Weeks Later I Got

I had a flu and two weeks later I got sick heart palpitations and general fatique. The doctor in the hospital said I had a mild micocardit he gave me anti inflammatory drugs for chest pain and bisop if I needed it for palpitations. I still feel tired and have palpitations but not all the time. I have a chest discomfort. It's nearly 4 weeks now how long before I feel well
