Wow, after a few reasonable days I had a really bad night last night. I was at a work away day yesterday, so maybe I did too much. Was in quite a lot of pain last night, but a strange pain more like tingly pins and needles in my arms neck, back, legs. It kept me awake most of the night, I've had like 2 hours sleep at most. Back at work this morning, not much change really. I'm taking it easy today, I'm at work but I've got lots of light paper work to do, so just plodding through in a zombie like fashion. I'm going to head off early tonight.
