My dad has stage four bed sore on his buttocks, he is in a nursing home with somewhat good care. you know what nursing homes are like. What can I get to get this heal and close faster? He is 81 years old a diabetic, cancer patient, heart patient, high blood pressure and properly anything else you can think about he has. I am very concern this is not healing and he could die from this. That is how my grandfather died from the bed sore infection. I really need your help please, my father means the world to me and his grandchildren. Thank you.
