The interesting thing for me about going to bed with and waking up with the same headache for five consecutive days was how intensely aware it made me of my own body. When it got to the point of hypersensitivity and I was getting goosebumps from almost any sensation at all, I was so physically self-aware that I became almost unwillingly focused. It was like a very strange sort of meditation, where any daydream that began or song that started to get stuck in my head or even passing thought quickly disappeared. The trick was, instead of that engendering a feeling of release or anything of the kind, it was as if it was being forced upon me. And that was an unpleasant feeling on par with actual pain of the headache itself.
