What is CSF and what does it impact?
 

My MRI report noted a "prominent retrocerebellar CSF which may represent a prominent cisterna magna or arachnoid cyst." Does this mean something and what would the symptoms be?

I'm waking up 30 to 60 times per night every night without any relief. I think it's from neck aches and discomfort. Not 100% sure though. Anyone have any input if this CSF has anything to do with it? Also picked up stenosis on C3-C6. Thanks.
