Usually when I am focusing on it, I can feel that my body is ever so slightly vibrating internally, but it is seemingly impossible to feel from the outside. For example, sometimes if I am resting my arms on a table, I can feel slight tremors and my arms that seems kind of like a rushing sensation, as it is also vibrating very quickly, not like normal panic attack shaking, and I feel like it’s something that’s going on 24/7 even though I don’t always notice it, since it is barely noticeable. Is this something normal that happens to the body as a result of past anxiety? Thanks
