I'm really worried because my whole body seems to vibrate with my heartbeat, and I can actually see it in my stomach and hands. I've done ECGs, two TMTs, and an echo, and they all came back normal. I also feel this pressure on the left side of my chest, plus irritation in my throat that's been going on for more than two weeks now. I'm not sure if I should go for another echo or not. I also have a vitamin D deficiency and am taking weekly sachets for it. Do you think it's necessary to take calcium tablets with it? Any advice would be really appreciated.
