I have been to the emergency rooms two times in the last two weeks. shaking, tingling in my foot, palpitations, cold, dizzy, disoriented & confusion. my ekg, x-ray & blood came back fine. i dont know what to do. what can it be?

Anxiety would be my first guess but need to discuss with your local Dr. If you don't have one you can set up a personal physician so you see the same time Dr every time at HealthTap as a start.

Follow up in the outpatient setting is critical in trying to explain your symptoms as workup will be directed at finding a diagnosis, rather than ruling out life threatening conditions, as typically done in ER. While anxiety is always contributing to some extent to such symptoms, it is likely that in your case they have a medical root.
