My days off

 From time to time, I may not be writing; here is an article explaining some of the symptoms I suffer from http://en.wikipedia.org/wiki/Occipital_neuralgia
   Putting it in terminology which is easy to understand:- The least painful is like a bad headache on the top of my head. Stage 2 is like having somebody put a pen in your ear, push on your eyeball and squeeze your head and the worst case is like the USS Enterprise going into warp, with stars flashing around and yellow stripes on the walls.
