Pressure in head

The morning started off good, but now my head has so much pressure in it. For me, the pressure hits, then the nausea, then my vision goes blurry and finally the headache sets in. Does anyone know what exactly is the cause of the pressure feeling in the head?

This link best explains why we have headaches. I hope it helps.

Hey Susan, sorry I'm a few days off here. :) I was looking for answers for me and found your posting. I have been icing my neck because of the pressure. I also noticed that depending on how I "positioned" my head I could improve or worsen the headache. Does that make any sense? I'm finding it harder and harder to sit comfortably on the couch. I've noticed headaches get worse if I drive over an hour so I'm thinking it has something to do with supporting the neck? I shows signs of my cord being compromised so I had the CINE MRI done. Unfortunately I don't have a Neurologist anymore so I need to find someone that will read it correctly. Let me know how you are doing? I hope too that you don't have to go back in for surgery. I'm so sorry that you are miserable. Take care.
