What does having small headaches, dizziness, blurred vision, and a loss of balance indicate?

Maybe benign: Although migraine syndromes can include problems with dizziness and changes in vision, the loss of balance is concerning, as this could indicate inner ear or brainstem problems. Since this could be associated with anemias, medication rxtns, and thyroid problems, or even sinusitis, best to get examined and diagnosed.

Anything: Headaches can come from fatigue, sleeping too much or too little, eye strain, sleep apnea, snoring, being dehydrated, having chronic sinusitis or allergies, too much caffeine or over the counter headache medication, high blood pressure or something more serious like a tumor. See your doctor and get checked.
