I guess its like asking if a mechanic would know the difference between a flat tyre and a blowing exhaust. Any cardiologist would know the difference and not confuse one with the other :)
Yes anxiety can easily cause an enlarged heart but it takes time.
It was not a cardiologist, I guess I should have specified that it was a general practitioner. I haven't seen the cardiologist yet. I have an appointment scheduled though. It's just that I have been feeling this way for a long time and according to the doctor I seen pericarditis usually last less then 6 weeks.
Thank you for answering.
well when you see the cardiologist, mention your idea about pericarditis, that way there can be no misinterpretation. Good luck and I hope it all goes well.
