I just PMed you btw. This actually sounds like a migraine disorder. Alot of GPs say "migraine only causes unilateral throbbing, nausea, and photophobia." Nowadays, alot of neurologists realize it can present in many more ways. I have had your symptoms before (neuro exam, annual eye exam, and brain mri all clean!), and I also struggle with frequent vertigo (my inner ears are fine--been tested), fuzzy headedness, and light sensitivity. Saw a migraine specialist finally and he said "Migraine/Anxiety associated dizziness", but he also said those pesky headaches i used to have days on end were migraine. Hope this helps!
