I go into hospital for an op on Tuesday (Deviated Septum and sinus
opening) typically over the last couple of days I have been all bunged
up with a lot of stuff going down my throat - but as of yesterday I
have also been getting an awful headache on the top of my head where it
feels like someone is stabbing me - it comes and goes within a few
minutes or so and comes back later in the day...could this be sphenoid
sinusitis?

I suffer with anxiety though I am not worried about my operation at all
- but this headache is like something I haven't had before.
