I'm under a lot of stress. I found out yesterday my dad has a aggressive form of prostate cancer, my house is going up for auction next week, I have a 18 month old son who is on the constant go, and I've been having heart fluttering for 2 days with some pain in my chest, headaches everyday, and feeling dizzy. I have had a heart murmur since I was born but this fluttering is kind of bothering me now. I know it's a lot to deal with but should I get checked out or be concerned?
