Go to social security and try to get medicare help immediately. Go to a great hospital and ask for help. I don`t think they will turn him away. Try anything to get help at a good hospital.
Go to the local newspaper and ask for help by way of a story printed in the paper.
If he is a veteran go to the local American Legion, VFW ALSO AND ASK FOR HELP. That is what their for.
Please let me know his status.
