I wonder if I should be worried. According to this chart, I appear to have had about 37 heart attacks this year...
Upper body new/unusual pain? Yep, had that about 4 times lately. Sudden cold sweats? Sometimes a couple days a week, and sometimes a couple times a day. Nausea & fatigue? Every day for the last month. No wonder it's so hard to diagnose heart trouble in women--my doc listens to my heart and lungs EVERY visit and has never said anything about reduced or unusual heart and lung functions.
I do have a stress-activated arrhythmia of ventricular origin, but we've known about it for 20 years because in my case it's due to having had Graves' Disease as a teen and going undiagnosed. One of the permanent side effects of Graves' is ventricular arrhythmia developing in the early 20s; mine started acting up when I was around 22.
Ladies of the Cellar, if you have health coverage and any concerns after checking this chart out, get your heart checked out!
