Hi my mother 65 had 2 strokes in 4 months she is unable to speak or move and has numerous bedsores one of which had been cleaned surgically. She is diabetic and has high blood pressure. She s been treated for acute renal failure and various infections. her iron levels are low. dr has put her on end of life care as they feel that there is nothing ore they can do for her. She now has dry gangrene in her feet and legs, the dr says there is no bloodflow to her legs, how long does she potentially have to live?
