hey all, i need some advice/help/someone to listen. i have not been diagnosed with POTS. when i was about 15 i fainted for the first time. i got up off the sofa, started walking to the bathroom, and just blacked out. this happened on and off throughout high school and college. sometimes it happened as little as once a year, sometimes once a month. i would mention it to doctors and they would say it was low iron, or hormones. i never thought much about it. now i am 24. i had a sinus infection about three months ago. ever since i have been having these fainting spells once or twice a week. every day i get dizzy when i stand up, move my head, or walk. i get up, start walking, my vision blurs, heart flutters sometimes, and i fall. i finally went to the doctor about a month ago. he did an EKG and i wore a 24 hour heart monitor, and he did blood work. they showed nothing. he told me to drink plenty of water, eat 3 squares a day. i did this and about a week later i was reaching up to get cereal out of the cupboard and everything went fuzzy and i fell. so i went back to the doctor. he took my BP lying down, sitting, and standing. it was okay. he did say that my heart rate increased greatly upon standing. i have a tendency to have lower blood pressure, usually around 95/60. so he sent me for an EEG and MRI. that was yesterday and i am waiting to hear. for some reason this is really depressing me and i can't figure out why. i feel tired all the time, and am very easily agitated. i feel like people think i am making it all up. thanks for any support. sara
