Hello,ive been waking up with sores on my legs and feet, its like someone's been scratching it badly while i'm sleeping, ive checked under my fingernails and i cant find any blood/skin, so i dont think its me that are scratching while being asleep. ive got no idea what this is, ive been having it for several years, and the doctors cant find anything, ive been given alergy pills (cetirizin) but it doesnt help at all.Kim
