Another avenue to check is your electrolytes. My mama & I both tend to get imbalanced if our sodium dips - especially in the summer. Sometimes it's remedied with something as simple as Gatorade - but my fiance gets a kick out of my having an "anti-dizziness" medication on hand in case the G-ade doesn't work! "She's so dizzy, she has to take pills for it!"
I'm glad that you're seeing a doctor, texas*princess. If it's not an immediate diagnosis of an inner ear infection, demand a complete chem panel!
