Hi, im a 19 year old female and up untill a few months ago i was perfectly healthy. Since July26th ive been dizzy and lightheaded. Also ive been feeling very weak. This is on and off and some days i am fine, but other days i cant get out of bed. Ihave had every test under the sun. CT ,blood work,thyroid, electrolyte , ear pressure..EVERYHTING was perfect. I just dont get what this is, ive been to my Family Doctor so many times i think i am starting to annoy him. Also ive been to an ENT (ear nose throat dr). Im going friday to have a Balance (ENG) Test done. ANyone have any ideas what this could be?! Help!!!!!!!!!!!!
