In May I began to have dizzy spells which coincided with a sore throat and earache, which cleared up on their own. However, dizziness and fatigue continued for several weeks. 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. Could allergies have led to a sinus infection? Can the sinus infection cause dizziness and fatigue?
Due to the holiday weekend I haven't been able to call my doctor, but after 3 prior visits he's never suggested sinuses to be a cause.
