Hey everyone, just a short heath summary. I started getting sick 2 1/2 years ago after having my son. It started with daily fevers, weakness, gastropherisis constant nausea, aches and pains and racing heart along with chest pain. I went to several doctors and specialist Who couldn't seem to figure out what was going on. In April I flew across the country to go to the Cleveland clinic in Ohio. I had a tilt table test and was diagnosed with Nueropathic POTS, I also have an Arnold Chairi malformation of my brain which has contributed to my autonomic nervous system malfunctioning. Anyway I go back next month to have a QSART test done, an autonomic battery and a hemodynamics nuclear test done. I am terrified of the last test as I have a bad reaction to contrast. I was just wondering if anyone has had the test done and what to expect. Thank you for reading!
