For a while now, and I ve never gotten this checked out before, my heart does this thing where it speeds up slightly I guess. But it feels like its skipping beats (Yes I know that s impossible because Id be a walking heart attack ) but it s not painful it s just uncomfortable. But I know its abnormal. I just don t know if I have a heart murmur or what? I can t explain what it is or what happens I just know its uncomfortable and I just try not to move when it happens so it ll pass. Any suggestions as to what this could possibly be? I m dying? You re original.
