You need to be checked by a doctor. If you were supposed to have an echo 2 years ago and didn't do it, you still need to have it done. The heart isn't something to take lightly. Don't think that you are "just fine." When I was 34, I thought I was "just fine", but then I volunteered for a genetic Heart Study where part of the study was to have an echocardiogram
done. My echo came back abnormal. Turns out my heart didn't beat as strongly as it was supposed to, so now I take heart medication. My condition can eventually turn into heart failure
, but because it was caught, I can now take medication to help avoid future problems. With the medication, I now have a normal echo.
So, you be sure to go to the doctor right away and get checked out before you do anymore exercising.
