I have a concern. I am a basically healthy 19 year old female in nursing school. I recently have been having problems where my face will turn really head and feel very hot, but my arms and legs etc. are still cool. It makes my head hurt really bad. I also go to the gym and I dont know how accurate the heart rate monitors on the cardio machines are, but when I am exercising, my heart rate will go from 170 to 80 in less than 3 seconds. I got on several machines, and they all did this! I dont know if I should be concerned by this or what to do. I also get dizzy often, but was told earlier by a nurse practicioner that I just had fluid in my inner ear. I"m not sure what to do.
