hello. I am an RN. I was at work this morning standing getting report when I suddenly became lightheaded, dizzy, had numbness and tingling in bilateral arms and legs, got really hot and sweaty and according to my coworkers I was pale and my lips were dusky/slightly cyanotic. I sat down and drank some orange juice and had some crackers and cheese. Co-workers got vital signs on me which were blood pressure 105/68 pulse 58 and after sitting for a while O2 was 100%. Blood sugar 15 min after juice and crackers was 90. I have had similar episodes in the past but have not seen a doctor because the episodes are not frequent. I also wear a fitbit and my typical resting heart rate will drop as low as 46-48. Is this something I need to be concerned about or seek treatment for? I am only 28 years old. I work out 4-5 days a week and have a relatively healthy diet.
