Hi, my mother has numerous illnesses. She is on dyalisis, she is on a trachea breathing machine, her blood pressure runs low to the point that her heart stops, she has a bed sore on her lower back, she has an infection and now I think her legs and arms are stiffening because they try to straighten them out and she resist that motion. She has only been there for 5 months and I wanna know is that normal.
