Wondering what to do for pressure sores. My mother has one on each butt cheek. They seem to be healing but then she goes to the bathroom and there are spots situated between the butt cheeks that bleed. We have tried triderma cream emuaid cream which appear to work but she not able to stand on her own and in a great deal of pain due to spinal stenosis and bone on bone in both knees, she uses adult diapers but because of pain does not like to stand up so we can change them more than twice a day. What to do??????
