Thank you Peacheysncream and Mark in Idaho. You have given me many things to think about. I'm having a sleep study next week. It would be nice if a headache would come on while I'm hooked up to all those monitors.

I got my first headache 3 weeks after MVD surgery which involved draining my cerebral fluid, so I've always thought these headaches had something to do with CSF or increased pressure.

I asked about raised ICP, but was told that it would be more constant. The headaches were every 4 weeks or so, but now I'm getting one every two weeks or less. Do either of you know if raised ICP can come and go?

I really appreciate your responses. I hope you both have a great weekend,
Cheryl
