I have eczema, and I feel like most people who don’t have it cannot understand the experience of giving in to the urge to scratch affected skin after a period of trying to resist it. The best way I can describe it is an orgasm, the length and intensity of which you can directly control. It really is that intense. Why would we have evolved to have such an extreme pleasure response to something negative? And yet the effect of scratching on the skin seems very clearly negative. As a sufferer, it’s psychologically very difficult and confusing.
