<s>[INST] Hi can you explain fluttering in the back of the brain with like either quick jolts of dizziness or long drawn out moments of dizziness that seem to be caused by these brain flutters. They scare me!!! I go to see a neurologist on Fri. and I have had a MRI done but this is due to very extreme head aches. What questions should I ask should I request a special kind of med for this thing should I be worried. [/INST] Hello!Welcome on Healthcaremagic!Your symptoms could be related to occipital neuralgia. If your brain MRI is normal, I would recommend performing a cervical spine X ray study and inflammation tests (complete blood count, PCR, Sedimentation rate). Hope you will find this answer helpful!Kind regards, Dr. Aida </s>
