I know my Mum is nearing the end from everything I have read. I came to visit this weekend and significant difference to when I last saw her. Has gone downhill the past week. New symptoms include swollen feet and brown and minimal urine, as well as being extremely weak. I think she will now be confined to bed, as moving her seems like wasted energy. I am wondering if the brown wee and swollen feet are signs of kidney failure, and how long she might last. I have to travel home tomorrow and am worried about leaving her. Should I stay?
