Has anybody's attacks changed in the way they come. I used to have the tingling in hands arms legs with hyperventilating rapid heart beat. Through the yrs I have good yrs without them. Now I feel a disconnect before they come lightheaded, nauseas and dizzy with fog and a sense of doom. Blood pressure seems to rise like I’m gonna pass out but I don’t then I might get the rapid heart beat with a cold feeling inside my left chest area.
