I have had Vasovagel Syncope---was told I would eventually grow out of it (still waiting for that), migrianes, kidney stones, and endometriosis since my teens. I was diagnosed with chronic leukopenia and anemia by my hematologist and given multiple infusions of iron, various meds and had a bone marrow done. I am gluten free (for almost a year now and it has not made a difference), GMO free (another wholistic suggestion), and uterus free (the anemia became too difficult to battle with a never ending menstral cycle). I was told I had a "retro-virus." Although my white counts remain abnormally low, I do not get ill. I think the few white cells I do have are super white cells. I always thought the POTS diagnosis was just the FINAL diagnosis---I thought it just explained everything I have been dealing with since youth all thrown together in one POT (so to speak). I am new to this site. Wish a couple of the doctors I have seen in the past would educate themselves regarding this disorder. I have been dismissed time and again by doctors that are considered the "top in their fields."
