I'm chiming in here just from a different perspective. Chinese medicine depicts any kind of moving, itching, twitching or anything that comes and goes like a light switch being turned on and off contantly.... especially on the skin as WIND and has a lot to do with the actual organ (liver). Does not mean that the liver has any serious disease for those who might get scared hearing this. The liver is the metabolic factory of the whole being and has over 500 daily functions. It can and does get sluggish and over loaded and then sometimes this gets expressed on the skin like urticaria.43RichyThe43rd
