Ive been having these same symptoms for almost 6 months. Ive been tested for thyroid, STDs, Lyme, Vitamin D, Vitamin Bs, Liver/kidney
function and the only thing that came back not normal (21 when the range should be between 40-80) was my vitamin D. My doc put me on 2000IU a day with daily vitamin+supplement. She retested me after being on it for 2 months and it only went up to 28. She doesnt want to up my supplement but I did it anyways.
