Does anyone have this, went to the cardiologist gave me a ultrasound of chest and some nuclear test were they inject you with some clear liquid to see how the heart is pumping and said I had myocarditis. He put me on monopril. He said its was most likely caused by a virus but I haven't been sick. I was having chest pain with arm,neck, pain and a bit shortness of breath.I was told that their have been cases of sudden death caesed by this. I also have TMJ and suffer from anxiety.
