question: I have been sick for 3 months now and have been to "the best of the best" in nyc. I started at a thyroid doctor then stomach doctor then a new internist and then I was tested for POTS at NYU med. which came back negative. All they found was that I randomly get heart palps, don't get enough oxygen & have anxiety and depression. They told me to do Yoga. I have home now and have been throwing up for the last 3 days, feel light headed and out of body and get rushes to my head even sometimes when I'm just standing of turn my head, I will get a strange jult of pain with the rush. What is this?! Has anyone else had this? I am worried even after all of my testing they missed something.
