I can not shake my head as in No. Yes is a safer motion. It has to be a personal evaluation. Some of us can and others can not. Watch for symptoms like spacial disorientation, a metallic taste in your mouth, and any of the common concussion symptoms. I would be cautious about continuous head movements. The cumulative effect of head moving can be delayed. You may not notice an effect from shaking your head until hours later.

Just be cautious and aware of how it makes you feel.

My best to you.
