“The trouble with chronic pain is that it is so easy to become accustomed to it, both mentally and physically. At first it’s absolutely agonizing; it’s the only thing you think about, like a rock in your shoe that rubs your foot raw with every step. Then the constant rubbing, the pain and the limp all become part of the status quo, the occasional stabbing pain just a reminder. You are so set to endure, hunched against it – and when it starts to ease, you don’t really notice, until the absence washes over you like a balm.” ―Robert J. Wiersema
