Especially when the body is damaged and in pain, there is constant, dynamic "bracing" to handle pain. It's not your postman, but same lack of presence. My mind is busy with not wanting to be here, and runs back and forth with anticipation or dread of the next movement. What helps, as usual, has been to slow down enough, be complete (blissfully that's not conditional), and try to apply the principles of body being (relaxing, centering, grounding, being calm, feeling the whole body). It becomes more accessible because of feedback: it works! It still won't happen naturally and I have to keep on training the principles, but I am quicker at pulling them out of my back pocket now. No fantasy here, the damage doesn't go away, healing takes time, but much of the tension around rejecting the experience of pain and expecting to move as I wish I could, that's just proven detrimental. My comfortable, automatic patterns of sitting, standing, putting on clothes, driving - they don't work. But as soon as I reset to body being principles, a world of adaptations and workarounds opens up.
