How can I heal a very stubborn 'pressure area. It just the first layer skin now. grandma got this a year ago while hospitalized after a hip break. It was actually open and draining. With the Home health nurse help we got all that cleared up and the skin was pink but that only lasted a few weeks and now it's red and very tender. It on her bottom just at the top of her buttocks. She stays dry and while in bed she on her side most the time. She does sit up in her wc usually all day. I always cover it when we go out in case she does get wet. I've put everything I know on it.
