Hi Maggie,
I have difficulties with my heart. I have had quadruple by-pass surgery. I am negatively impacted by congestive heart failure, AS and am bi-polar. First, try not to be scared to death. That truly does not help. Have you had an EKG, and other tests from a good cardiologist? I recently joined this group and have found the support one receives from others to be a blessing. I have been frightened and scared before. None of that helped. In fact it made things worse.
Maggie, call your doc tomorrow and tell her how you feel. For your peace of mind see if you can find strength from within and from your support group.
If you want to talk about your concerns, I am available.
Don't be afraid, we are all in your corner.
Joe
