The palpitations seem to be more persistent after dark. There's also a strange feeling in my chest that I cannot quite pinpoint as tightness, pressure or anything else. There's also the occasional muscle twitch in my heart area and lower abdomen. Also keeping in mind, all of the things I mentioned seem more frequent on the left-hand side of my body.
Also, I seem to be a bit trembly sometimes, as though every time my heart beats it reverberates throughout my body quite visibly.
I've got a doctor's appointment soon, but any insight now might help me relay this information better to a doctor.
