After eulogising about a lack of pain I am having the most painful and uncomfortable night yet. Obviously the bliss was to be brief and very soon I found everything aching, starting with my rather overworked legs and then my whole torso and arms started screaming out. Coupled with which the room I'm in is suddenly very cold and so I have extra blankets and am wearing a jumper.
I've relented and asked for some more Tramodol, one of the opiate painkillers. Hopefully it will kick in soon and I'll be able to have another go at sleep. The combination of total body pain, cold and extraordinary levels of tiredness is awesome.
