It started as a normal headache, then went just to the right side of my head. As the day went on it got worse and worse until my vision was affected and I had to lie down all evening. I was feeling nauseous and hot/cold intermittently.
Next day it was much better, vision fine no nausea no hot/cold but still the pain on the right side of my head.
The pain has stayed at variable intensities for nearly 3 weeks now, and for the last 3 or 4 days, I feel a heavy type of sensation around my right eye and side of my nose. The inside of my mouth feels slightly numb. A couple of times the pain has woken me from my sleep.
I've tried taking some decongestants thinking that perhaps my sinuses were a bit bunged up, but it's no better.
I've been to my GP, who has said it if carries on for 3 more weeks then he would consider referring me on (he wouldn't say who to - it would depend on the symptoms at the time).
I've been good and not googled my symptoms as I'm sure it would tell me that I have something awful!
Does anybody have any idea what could be causing this (apart from a brain tumour which I'm slowly convincing myself is what it must be)
