Mum has a habit of scratching her upper arms, legs, head and shoulders until she bleeds. Her blouses always have blood on them and her slippers are stained from her legs bleeding (on blood pressure medication so bleeds easily) Armchair, carpet & cushion are also badly stained. I am really worried about infection. Mum is doing it as a habit, rather than from irritation so I know stopping the behaviour is nigh on impossible. Any advice lovely fellow carers?
