Currently fearing I'm sick but the doctors say I'm fine
So I had a cold like 3 weeks back that took like 10 to 14 days to fully pass. But nothing too serious. Pain in my throat, a little cough, running nose. During the time I was sick I once or twice had to do physical work which made me worried that I have overdone it and risked a myocarditis. On one day I felt a pain in my chest that didn't want to go away so. I went to the ER. Also my pulse was going relatively high fast and went down really slow.
They checked blood, did multiple ecgs and an ultrasound of my heart. The doctors said I'm fine but I still feel unwell.
I don't know if I'm fit again and sometimes during the day I can feel my heart beat. Today I felt a little dizzy and I'm afraid the doctors may have overseen something. So I'm very anxious to start working out again.
Do you have any advice?
Maybe some experiences regarding myocarditis and other infect induced heart problems?
