Has anyone experienced brain zaps due to anxiety and not medication? 

I have been convinced the last 4-5 days I have a brain tumor. I thought I was dizzy, but it’s more of a dizzy surge through my brain. Not so much room spinning or light headedness. Sometimes I feel slight lingering dizziness after the initial surge, but sometimes it’s just the surge and nothing else. Usually it causes me to spiral into anxiety though. I have bad health anxiety and have been absolutely horrified that something is very wrong with me.

Is this a brain zap? Would getting on medication help me? My anxiety has been very bad.
