The dizziness resembled being carsick,
with lightheadedness and
occasional moments of nausea and
feeling faint (but I never passed out). I had a CAT scan and blood work twice,
and so far no diagnosis for the dizziness/fatigue. It got better for a few weeks but last week I began to have dizzy spells again,
this time accompanied by maxillary sinus pressure. I had just switched allergy medications,
from Nasonex to generic Flonase,
right at the time my symptoms returned.
