It was my first posting in the RAF. RAF Lossiemouth, Morayshire. I was riding out to one of the hangars to collect some film to be processed, when I was hit with the late summer light bouncing off the tarmac. From above, the tarmac looks green - a wartime paint - but from ground level it's concrete grey.
I had turned the corner of the hangar, and caught the full Summer sun on my face. The only analogy I can think of is being hit with full beams from a lorry.
It was so painful I almost fell off the bike I was riding.
Since then it has been a constant companion; I can tell when it's coming. The pain starts as a slight headache - always over the right eye - travels to my ear, and up to the back of my head before travelling down the right side of my face, and into my shoulder.
As with every illness the symptoms cannot be defined, as each sufferer has their own. I can only describe my symptoms to you.
The main area of pain is my eyes, they feel as though someone is forcing their thumbs into my eyeballs. The pain is unbearable, and usually lasts hours.
I have to lie quietly in a darkened room until all things calm down. Behind my eye lids, the scene is similar to Star Trek when the Enterprise goes into warp, and the stars fly by.
If I open my eyes, all I see are bars of yellow light flashing around me.
Last night was Booktrap's 1st anniversary; I was scheduled to take the 12:00 (midnight UK) slot, but I had to cancel as my migraines kicked in. Instead of being awake until about 2:00 am, I was asleep by 11:00 pm, which is rare for me.
