Hey guys for some scray reason my brain feels like its freezing to a point where it hurts and makes me feel like I'm turning into a zombie mush.  You know when you drink a cold drink to fast and get a brain freeze, well I get that without doing nothing and it stays with me.  I had mri but they didn't find nothing.  I recently passed out and got up feeling cold and shivering.  My brain feel like it was sore and throbbing. 

Any idea?
