Hi,
Thanks for writing in.
Your symptoms of light sensitivity, pain in head and neck, light headedness, visual and auditory changes are very suggestive of migraine.
It is good that you have not had another attack ever since. However I would advise you to be careful while consuming alcohol, processed meats, cheese, MSG, artificial sweeteners as these are known triggers for migraine.
Take care!
Could be a severe head ache, could be a migraine, migraines are debilitating. Light sensitivity often accompanies migraines as does irritation with sound. What you describe as everything going white would concern me, as well as hearing funny. I can never focus when I get a migraine. I have to get alone in a hot tub, hit it with meds, and lie on a bed wedge never flat. This could be anything from an ear(outer/inner) infection, allergies, chemical imbalance, to an onset of migraines. If it happens again, your symptoms are severe enough to justify seeing a doctor. Hope this helped take care.
