I am concerned for him. He is 88, has Parkinsons and it seems to be getting worse. He is having trouble walking and his hearing is very bad. He is also diabetic. His doctor retired several months ago and his daughter in law finally got an appointment with a new doctor for end of November. I am afraid that he needs help and am also afraid that he will fall because his legs keep "going numb". One son lives in Florida and the other son lives a few miles away. I don't want to get in the middle but am concerned. I am the one who sees him daily. I cannot be the only person responsible for his care. He has become dependent on me. What can I do? Please help.
