Well if anyone is recently dealing bed sores. You need to build up the inside and treat the outside. You need to make sure that he or she is getting enough nutrition and protein. Protein is needed to build the body. On the outside your need to treat the sore with the proper wound dressings, and with good incontinence products to keep the skin away from urine. If able you need to have them move around. If unable to get up. An Alternating Pressure Mattress will automatically shift the body around enough while lying down.
