I just went and visited my mom and dad at the NH. I'm so upset about how things have been with my dad the last few weeks. First I realized how much weight he was losing. He was not eating because he could not feed himself. I got that taken care of and he is receiving pureed food and is being fed, I knew he had a bed sore. He has had them for years. They changed his mattress on Sunday to an air mattress. Today I saw the sore and it is about 4 inches in diameter. I freaked out. They told me that it just all of a sudden came up. That it was small and then just all of a sudden got big. My question is if this is possible. They said at end of life sometimes the skin will do that. I just don't know what to do. I can't be at the NH all the time, but it feels like I need to be for proper care.
