I'm usually in the Chronic Pain forum but I'm helping out over here too for a bit. I'm sorry for the symptoms you are having.
Don't feel bad for posting here! I completely understand your concern.
Have you made an appointment with the cardiologist?
There are so many things that can cause heart arrythmias. You might want to do a little reading on the possible causes.... and symptoms....... etc. Here's a link I found: www.medicinenet.com/arrhythmia_irregular_heartbeat/article.htm
That said, while Google can be very informative, I also wouldn't read too much - as it can also get you worked up and even more confused! (I say that from experience!).....
Having some chest discomfort can be a part of heart arrythmia. The cardiologist might have you wear a Holter monitor - which you wear from anywhere from a few hours up to several days - and it gives a good overview of what your heart is doing. There are also many other types of tests/scans that can be done.
That said -- if the pain gets too bad - don't hestitate to get yourself to the ER. It's better to do that...... than to let something go.
Let us know if you have an appointment scheduled or what else the doctor said. Did she explain anything else to you?
Hang in there..... I hope you feel better. --Tina
