Wave sensation in head....anxiety?

I'm 29 and for the last 5 months I've had stress and anxiety which has turned into GAD/health anxiety about a brain tumor.

I get alot of physical symptoms, headaches, tension in shoulders, neck and face.

Recently I've been getting a weird wave sensation through my head/brain it's not painfull and lasts a second but drives my anxiety up not end..it's not a brain zap and happens a couple of times a day out of no where. I suspect it has something to do with muscle contractions in my neck but obviously my anxiety is telling me it's a brain tumor or mini seizure.

Has anyone else ever had anything like this?

I think I know what you are talking about and yes I’ve had it. Hope u feel better! 

Hello,

Whilst at work sometimes when looking at my monitor I feel a srange wave through the head which I can describe like being in a lift which suddenly drops and makes me feel off balance and dizzy. Does this sound familiar ? Am currently on meds for anxiety sad had MRI scans etc and found nothing wrong physically. I actually am feeling this horrid sensation today and can't wait for the day to be over and back home. At weekends I have no such problems....
