Mum has been banging into things and tearing her skin(which is like tissue paper) for some years now but in the last fortnight it's taken a new and more worrying form. She cut her leg in her room at the nursing home - how, she can't remember - and the district nurse has been looking after it as usual, but the wound is now infected and the doctor has put her on antibiotics. Mysteriously, the other shin/calf is also covered in spectacular red, black, blue and purple blotches which seem to cover more of her leg every day. The GP is aware and doesn't seem concerned but I haven't seen her legs looking like this before - there's also a lot of fluid-like swelling in the foot and toes and strangest of all, the leg feels cold to the touch and not hot as you'd expect with an infection. Mum has no idea where the apparent injuries are coming from but she is complaining of 'terrible nights' and I am wondering if she is injuring herself while walking about in the night. The nursing home staff are concerned about the infected leg but haven't said anything to me about night time wandering. Has anyone else experienced this ? Mum is in (we think) late middle stage mixed dementia and until recently in fairly good spirits, but the appearance of the legs is obviously worrying her and to be frank it worries me too.
