My mother has had COPD for almost 15 years now and is in the final stages of the disease. But we aren't sure why she has so much pain in her back. It doesn't stay in one area, it seems to move around, mostly right up the middle of her back. Is this her lungs causing this pain? She refuses to have hospice come in, (because she doesn't like strangers in her house) so the doctor has her on percocet, but it isn't touching the pain. As one of the caregivers, I am just curious if this means she is very close to the end. She has been turning her oxygen level up to 5, having the air turned down to 70, and needs a fan blowing on her. The doctor has told her she can increase her predisone to 50 mg., she is on 40 mg. now.
