Vibration in the brain

Has anyone experienced a strong vibrating/buzzing feeling in the brain (like your brain is shaking) leading to confusion, fullness, lightheaded and dizziness? Just wondering if this is something to bring up to a doctor or ignore. Friends suggested it could be migraine related, partial seizure or tia. Been ignoring red flag symptoms lately because finding a doc to take Chiari seriously or to even order testing has been a nightmare.

Not sure if it's the same thing but on bad days I will have this sensation like my brain is bouncing around in my skull with every step. I hate it! :(

It felt kinda like a strong cellphone vibration right in the center of my frontal lobe. Only lasted about 5 seconds and made me feel like I was going to black out if I didnt lay down. Not sure what the trigger is but I get really dizzy and hear crackling in my upper neck if I move to quick. What did your NS suggest?

i get a vibration in like the back of my head, which my nl said it could be from the chiari.
