Whenever I get agitated/angry, or excited, revved up, I notice tingling in my arm/hand/feet, and start to just feel different, sometimes get some chest sensations. All of this worries me. Is this just a normal reaction to stress/anxiety, and adrenaline/hormones are being released, or could this be a sign of an underlying problem, or high blood pressure, or that im taxin my heart and cardiovascular system? Either way I m worried. But I ve been to the doc/ER countless of times in the last year, had bloodwork, ekg s and they say they re totally normal.
