Is it normal for an electric toothbrush to cause headaches?

Headache doesn't last long after I stop brushing but the whole time I am my entire head and vision vibrates until I feel dizzy and have to hurry through. The back of my head hurts and neck tightens up, is this normal and will eventually stop as I get used to the toothbrush or should I go back to the manual brush? Does anyone know what causes that?
